->''Priests clutched onto Bibles''\\
''hollowed out to fit their rifles''
-->-- '''Music/{{Coldplay}}''', "Violet Hill"

Books are great. Even if you don't like reading, you can use a book for any of a number of handy purposes. One favorite trick is to hollow it out and hide something useful inside it.

Most often this is a gun. Often the book in question is the Good Book. It [[GiveAWholeNewMeaning Gives A Whole New Meaning]] to "Guns and Bibles." Sometimes a character will go so far as to brandish the Bible while exclaiming "This will protect us!" or some similar line, only to open the Bible and reveal the weaponry within.

But the trick is flexible enough to be used for just about anything small enough to fit. Hand weapons, ammo, drugs, bottles of liquor, software, other books. Whatever.

If you're feeling clever, you can make sure that the object you are hiding goes into a hollow book of an appropriate genre or title: A secret locket in a romance novel, or a safe key hidden in a book on finance.

A book that is hollowed out and then glued into place on the shelf may be used to [[BookcasePassage hide a secret switch]] (or the book itself may even BE the switch.) If you're lazy -- or don't want to deface a book -- you can just pull the book out a small way and stuff something behind it instead.

This trope can be TruthInTelevision; check Wiki/ThatOtherWiki under "Book Safe" for examples.



* In the UK, a commercial for the board game ''Cluedo'' (aka ''TabletopGame/{{Clue}}'' in North America) showed Miss Scarlet retrieving the revolver from a hollow book in the library.

[[folder: Anime and Manga ]]
* In ''Anime/MaiOtomeZwei'', the "Book of Neptune," from which Nagi alleged to have learned about Yuna and the [=CHILDs=], was really a box with the Neptune Emerald GEM inside.
* A ''Manga/DetectiveConan'' case revolves around drugs hidden not in a book, but a "fake book" that has four sealed edges.
* ''Anime/JinRohTheWolfBrigade''. The protagonist keeps a Walther PPK hidden in a book.
* In ''Manga/PokemonSpecial'', it's revealed that Roxanne hides Pokeballs in the book she always carries.
* In ''Manga/{{Trigun}}'', a variation on the standard gun-in-the-Bible occurs when that big heavy cross Wolfwood has been lugging around with him everywhere turns out to not only to BE a BFG in its own right but to also CONTAIN a plethora of hand pistols as well. "It's heavy because it's so full of mercy", right...
* ''Manga/CardcaptorSakura'' started when Sakura opened a Book Safe: the hiding place of the the Clow Cards.
* In a flashback sequence in ''Anime/YuGiOh'', Mokuba uses this to smuggle Duel Monsters cards to Seto after their stepfather stopped letting him have toys.
* The spy team in ''Anime/PrincessPrincipal'' occasionally receives their mission files from a book in the library hollowed out to fit envelopes with wax seals. Another book, used by a different spy party, is hollowed to fit a camera, with the lens hidden in the ornate spine.

[[folder: Comic Books ]]
* In ''Comicbook/VForVendetta,'' corrupt priest Father Liliman pulls out a gun from his Bible when V enters the room.
* ''Franchise/{{Tintin}}''. In "Explorers on the Moon" Captain Haddock smuggles his whiskey on board the rocketship inside a {{doorstopper}} tome, labelled "Guide To Astronomy".
* Used in one ''ComicBook/LuckyLuke'' story - [[spoiler: a fake priest keeps a revolver in his hollowed-out Bible. Lucky suspects him and asks him to read some words from the Good Book...]]
* Red Hood smuggles a collapsible bow to Arsenal inside a bible in the first issue of ''ComicBook/RedHoodAndTheOutlaws''.
* In ''ComicBook/JonahHex'' #14 (original series), Jonah confronts a former gunslinger turned preacher who is killing bounty hunters. The preacher keeps a derringer hidden in his Bible.

* ''Film/JamesBond''
** ''Film/{{Thunderball}}'' features a sound-activated listening device in a book, which Bond uses to determine if someone has sneaked into his room while he's been out.
** One of the diamond smugglers in ''Film/DiamondsAreForever'' hides the goods inside a hollowed Bible.
** ''Film/LiveAndLetDie'' features the classic gun in a Bible.
* Used in ''Film/JohnnyDangerously'': as Michael Keaton is being walked to the Chair, in passing each cell along the way each prisoner hands him one component of [[IKEAWeaponry a Tommy gun which he assembles]] whilst walking. The last piece is in the Bible the priest is "reading" from. However, it's a fake gun, that falls apart mere moments after Johnny makes his escape.
* In ''Film/TheMatrix'', Neo keeps his illegal software inside a hollow copy of the real-world philosophy text "Simulacra and Simulation" by Jean Baudrillard. A real copy of ''Simulacra'' wouldn't be thick enough to hide that much stuff (it's not a very long book), so one can conclude that the filmmakers specifically worked this reference in as a hint to the nature of Neo's reality.\\
The illegal software was hidden in the chapter titled "On Nihilism", again referencing the philosophical themes of the film. It's worth noting that ''Simulacra'' and Jean Baudrillard are '''huge''' influences to the Wachowskis, as plainly evident in the sequels.
* In ''Film/TheAddamsFamily'' movie, the first stage of the secret entrance to the family vault is accessed by pulling a book out from a bookcase. The book's title? ''Greed.'' It's worth noting that ALL of the Addamses' books were like this, and that ''Greed'' was the most 'normal' book. ''Gone with the Wind'' causes a tornado when opened, and ''The Sun Also Rises'' emits daylight and the sound of birds.
* ''Film/TheShawshankRedemption'': The warden of Shawshank prison opens up the Bible to discover that this is where Andy has been hiding the rock hammer he used to tunnel out of his cell. Salvation, indeed. For that extra touch of irony, the hollow section begins halfway through ''Exodus''.
* In ''Film/TheGame'', Michael Douglas's character keeps a revolver hidden in a copy of ''Literature/ToKillAMockingbird''.
* One can also conceal documents between the inside of a book cover and its lining without removing any pages at all, as in ''Film/TheGoodShepherd.''
* There's a Western film where a large number of rifles are packed in ''crates'' labelled "Bibles".
* In ''Film/CatBallou'', Uncle Jed, disguised as a preacher, produces a knife from his Bible and uses it to cut the rope on the gallows as it is placed around Cat's neck.
* ''Film/AlienResurrection''. A Bible contains the modem Call uses to link to the ship's computer, presumably an [[NoPaperFuture electronic book]] with a 'traditional' cover.
* In ''Film/TheThreeMusketeers1993'', Aramis (who trained to be a priest) at one point pulls a pistol out of a hollowed-out Bible and shoots one of the Cardinal's guards with it.
* In ''Film/NationalTreasure'', Ben's dad keeps money between the pages of Thomas Paine's ''Common Sense.''
* The lead character in ''Film/{{Frankenhooker}}'' keeps a video tape stashed away in a copy of ''Literature/GraysAnatomy.''
* A book of Shakespeare with a gun in it is hidden within a Library in ''Film/HardBoiled''. Alan walks into the library, gets the book and kills his target. Then he replaces the gun and book on the library shelf and walks out. This was apparently done so the hitman would never be armed if he was caught, but the police find the book because of the blood on it.
* In ''Film/{{Kickboxer}} V'', the main character and his reluctant partner end up in prison, in which liquor is smuggled into cells by hiding the bottles into hollowed-out books, and delivering them through the library system.
* The short film ''WebAnimation/TheBackwaterGospel'' has the SinisterMinister open his Bible to take a gun out in the climax. And he's not that bad of a shot, either. [[spoiler:It doesn't save him though.]]
* In ''Film/SherlockHolmesAndTheSecretWeapon'', Holmes conceals the parts of Dr. Tobel's bomb sight inside a pair of hollowed out books.
* In ''Film/BloodrayneIIDeliverance'', the Preacher has a derringer hidden inside his hollowed-out Bible.

* The {{LARP}} of ''Killers'' mentions in the section on concealed weapons that players who hide their guns may have an advantage, but it's still considered legal self-defense to shoot the guy who's dropped into a firing stance and is pointing his geometry text at your heart.

* Although in ''Franchise/StarWars'' they don't use actual paper books very often, the Franchise/StarWarsExpandedUniverse has a couple of examples where a tiny hold-out blaster is hidden in a box in Imperial libraries that was supposed to contain datacards: ''The Complete History of Corvis Minor''. Supposedly the topic was so dull that no one who didn't know would choose to pick up the box.
** When Mara Jade finds one, it's because as the former Emperor's Hand she knows exactly where to look. Providing his secret agents with quick and covert access to a weapon in an emergency was precisely why the Emperor had this particular box placed in ever Imperial library across the galaxy, so when Mara had her blaster confiscated and needed a new one, she went to the nearest library.
** When [[ComicBook/XWingSeries Corran Horn]] finds one for himself and a number of other hidden library secrets, it's because he has luck and [[SentientCosmicForce The Force]] (which may be the same thing)--not to mention a lot of time to look around, as he was locked in the room alone. Corran being Corran, he cracks a joke to himself that if a blaster is the complete history of Corvis Minor, it must not be a vacation spot. Naturally, he follows up that thought by searching the remaining datacard boxes, hoping in vain to find additional weaponry.
-->''He eventually gave up on finding a "Complete History of Corvis ''Major''" that might hold something a bit more substantial, like, say, an X-Wing.''
*** In the later book ''Isard's Revenge'', [[BrickJoke the squadron ends up going on a mission to Corvis Minor]]. Just before they make the jump, Corran recalls the holdout blaster he'd found in the datacard box.
* ''Literature/{{Discworld}}''
** An odd variant that might be a subversion, a parody, or completely unrelated occurred in ''Discworld/NightWatch'', when a young Havelock Vetinari hid all the extant copies of a rare book on concealment inside the cover of ''Annals of the Great Accountants, Volume 3''. He thought the author would have approved.
** In ''Discworld/UnseenAcademicals'', Mrs Whitlow has cleared Ridcully's chambers of food and smoking supplies on the night before the big match. Luckily, his copy of ''An Occult Primer'' contains mints, tobacco, and cigarette papers... along with a note from Mrs. Whitlow that she didn't have the heart to confiscate those as well.
* Mike Ripley's AmateurSleuth Angel has a copy of ''The History of the United States'' adapted into a fireproof safe.
* ''Literature/JamesBond''
** In ''Literature/FromRussiaWithLove'', Grant has a gun concealed in a copy of ''Literature/WarAndPeace'', which ''[[ShoePhone fires if you press the spine in the right place]]''.
** In ''Literature/{{Goldfinger}}'', Bond hides his Walther PPK inside a hollowed out copy of ''The Bible Designed to Be Read as Literature''.
* ''The Bronze Horseman'' by Paullina Simons. The protagonists hide their stache of rubles and US dollars inside a book of Pushkin's poems. Disaster is barely averted when the family is burning all their books during the winter of the [[UsefulNotes/WorldWarII Siege of Leningrad]].
* In ''Literature/TheBabySittersClub'', Claudia mentions that she hides some sweets in a hollowed-out book.
* In the Creator/TimDorsey novel ''Stingray Shuffle'', a drug ring sells cocaine to its customers by running a book-shop and giving their drug customers hollowed-out paperbacks of a book entitled 'The Stingray Shuffle' (Chosen because it was an unpopular book that a normal customer wouldn't ask for) which had a gram of cocaine contained in the hollow. They sold so much drugs that way that they inadvertently triggered a revival of interest in the author, which caused a publicity event to be held at the shop, which caused normal people to accidentally buy paperbacks filled with drugs, which brought in the cops.
* In one early ''[[Literature/TheWitcher Witcher]]'' story Geralt, convalescing in the Nenneke's monastery, hides his booze behind the books in the library, because Nenneke disapproved of his drinking. Dandelion, visiting his friend there, promptly hangs lampshade on this trope.
* In ''Two Miles to the Border'' by Creator/JTEdson, the 'Daughters of the Lord' hide Colt Cloverleaf Pistols inside their heavy bibles.
* ''Literature/BlackWidowers'': In "The Unabridged", a valuable postage stamp is hidden inside a book. The puzzle for the Widowers is to figure out which book (or, at least, narrow down the selection).

* On ''Series/{{House}}'', House hides a secret stash of Vicodin inside a textbook on Lupus, on the grounds that he'll never need the textbook because [[RunningJoke "It's never Lupus."]] (Shockingly, in the fourth season, they did get a Lupus case.)
* ''Series/{{Lost}}''
** Eko finds pieces of a Dharma film in a hollowed-out Bible in the second season.
** A different version might be when Penny puts her letter into Desmond's copy of ''Our Mutual Friend.'' Knowing that he'll turn to that book at his lowest time, it kind of works the same as a Bible.
* In the opening credits for ''Series/{{Blackadder}} The Third'', Edmund is browsing through a library full of big, heavy history books with titles like ''From Black Death to Black Adder'' and ''The Blackobite Rebellion''. He then picks up a particularly hefty tome with ''Blackadder The Third'' on the front, raises an eyebrow at the camera, and opens it to reveal a lurid paperback with the episode title.
