Good day all.
I’m a new forum member and dipping my first toe into mystery writing proper. I like the general tone of the discussions I’ve read here and thought this community might help me. A while ago I wrote a story involving a police detective, even though the story itself wasn’t strictly what I’d call a mystery. Anyway, I’d like to bring the character back for a more traditional locked-room premise.
The problem: I’m stuck brainstorming for a MacGuffin that will work for me. There’s a crucial piece of evidence my detective needs to find. It’s hidden in a suspect’s house, and some trickery will be required in exposing it. (If that sounds a little page-one “Scandal in Bohemia,” well… I’m just getting started in the genre. If this story works I pledge to try something more sophisticated.)
Does anyone have suggestions for an item that
1) Is compact enough to be hidden out of sight without much trouble
2) Must be kept by the criminal, at least temporarily. In other words despite its incriminating nature, it cannot simply be discarded or destroyed immediately after the crime (let’s say murder, but I’m open to other options).
These are the ideal criteria for the story mechanics I’ve got in mind, but I’ve just been stuck awhile on this point. I hope I’ve got the right thread / am using this forum properly. All thoughts, practical and outlandish, will be gratefully entertained. Thanks!
