About this book
The clue is right in front of you—but can you spot it before you name the culprit?
In Minute Mysteries [Detectograms], H. A. Ripley puts you in the detective’s place. Each brief case presents a crime, a short scene, and a handful of suspects. Everything you need is on the page. Your task is to find the telling detail and name the culprit before looking at the answer.
These compact crime puzzles follow the fair-play spirit of classic detective fiction. A clue hides in an ordinary detail; a suspect may say one thing too many. There is no long plot to settle into. Instead, each case asks you to slow down, read closely, and build an answer you can defend.
What you’ll discover
- A case in minutes Step into a brief crime scene that gives your attention a clear, immediate challenge.
- Clues in plain sight Look again at ordinary details and decide which one deserves a closer examination.
- Logic over guesswork Test your suspicions against the evidence, rather than choosing whoever seems most shifty.
- The second look Read once for the story, then return to search for the detail that does not belong.
- Your turn as detective Make your own case before checking the answer, and see whether your reasoning holds.
Who will love it
Readers who love puzzles, riddles, and clue-spotting will enjoy this one, as will fans of classic detective fiction, teachers who want quick reasoning exercises, and anyone planning a party game.

The game and its rules
The book begins with a party game called It Stands to Reason. The host picks a few stories, makes a copy for each guest, and gives everyone about three minutes to study them. Each guest then writes down a solution and the reasoning behind it. The winner is whoever is right most often.
There is a second way to play. The host reads a story aloud, slowly, and may read it twice. After that no questions are allowed. The book points out that this version also tests memory, because a listener must hold every detail in mind without looking back.
