Word-trail mysteries with picture clues and a killer to catch.
Every grid is a room at the scene of a crime. Trace the words that belong there, tile to tile, borrowing letters from the picture in the middle. When every word is found, one letter is left behind. Collect them all and the case names its killer, its weapon or its hiding place.
Close the book and look at its edge. The grey frame of every page carries a sliver of the title, and the 75 leaves together spell it out.
