These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
The calm and slow Mr. Lightfoot disabling a goddamn bomb while Mr. Moulry complains and insults him all the way, and then scaring the daylights out of him by imitating an explosion. That second part doubles as a Crowning Moment of Funny.
Pretty much the entirety of "High Noon in Zephyr".
Fridge Horror: The quirks of a couple of certain characters become much, much Harsher in Hindsight when the identity of the killer is revealed. Specifically, Dr. Lezander's habit of giving people temporary nicknames. He did the same thing for Jews on the way to the gas chambers. And remember his wife's cute little ceramic birds? Made with human bones.
Tear Jerker: You won't get through this book without shedding at least a few tears...
The Woobie: Tom Mackenson becomes one over the course of the story, being horribly scarred by the murder and experiencing horrifying nightmares about the victim sinking and calling him. To add insult to injury, Tom loses his job as a milkman due to the construction of a supermarket and is forced to become a dishwasher.
Cory's friend Ben could count, too, what with being a prevailing dork even by his friends' standards and having to deal with his alcoholic dad.
