History Recap / ColumboS04E04

* OrgyOfEvidence: Columbo just gets more suspicious when he finds the DyingClue, the pistol, and a receipt for the pistol.

* CassandraTruth: Danziger did indeed steal a pair of latex gloves, steal a gun, fire said gun and hid those gloves in a rolled up fire hose. However Columbo has no reason to believe he would do this and when asked why, Danziger can't begin to justify it with a believable lie.

* FailedASpotCheck: For whatever reason, Hayden hides the murder weapon in a trash bin and doesn't toss the murder weapon overboard where it'll likely never be found and the salt water will help corrode it into oblivion. This comes back to bite him.

* MacGyvering: Since there's no forensic crew aboard the ship, Columbo needs to use graphite from a pencil and some paper to check whether the murder weapon has any fingerprints on it and use it to shoot at a mattress to catch the bullet so that he can compare it to the bullet that was found in the victim.

* {{Blackmail}}: The scheming Rosanna is demanding a payoff from Hayden, lest she reveal their affair. It's a bad idea.

* DyingClue: Hayden attempts to fake this, scrawling the letter "L" (for Lloyd Harrington) on Rosanna's vanity mirror with lipstick. Columbo isn't fooled.

* InsistentTerminology: A RunningGag in the episode, as Columbo keeps calling the cruise ship a "boat" only to be corrected to "ship" by the captain. In the end, when he calls the vessel that he'll use to get to the shore a "ship", he's corrected that it's a "boat", at which point he lets out a frustrated "to hell with it!".

* VacationEpisode: ''Columbo'' messes with the formula a little by having Columbo investigate a murder while he's on a cruise ship.
* YourCheatingHeart: Hayden had an affair, and is really regretting it.

Hayden Danziger (Robert Vaughn) is a used-car dealer and frequent luxury cruise passenger. On his last trip aboard the Sea Princess he met curvaceous temptress Rosanna Wells (Poupee Bocar), the singer aboard the ship. An affair followed. Unfortunately for the married Hayden, afterwards Rosanna started blackmailing him, threatening to tell Hayden's much richer wife Sylvia (Jane Greer).

* MacGyvering: Since there's no forensic crew aboard the ship, Columbo needs to use graphite from a pencil and some paper to check whether the murder weapon has any fingerprints on it and use it to shoot at a matress to catch the bullet so that he can compare it to the bullet that was found in the victim.

* PillowSilencer: Hayden uses one to shoot Rosanna.

Hayden resolves on murder. His clever scheme involves sniffing amyl nitrate to fake the symptoms of a mild heart attack. After he's put in the ship's sickbay, seemingly establishing an airtight alibi, Hayden sneaks back to Rosanna's cabin and shoots her dead. He attempts to frame Lloyd Harrington (Dean Stockwell), the pianist in the ship's band and Rosanna's jilted lover. However, Hayden didn't anticipate the presence of Lt. Columbo of the LAPD, who won a raffle and is taking a cruse with his wife. With the ship being several days out of port, Capt. Gibbon (Patrick Macnee) asks Columbo to investigate the case.

* TheGhost: Mrs. Columbo as usual, but particularly notable in this episode as she's on the boat with him. One sequence has Columbo wandering around the boat looking for her. Another scene has the captain pointing at Mrs. Columbo offscreen, getting on a shuttle boat.
