Closed-room mysteries you solve with a pencil. The CrimeWord cases, by Ada Finch.
Ada Finch writes closed-room mysteries built to be solved: a house, a storm, a handful of people who cannot leave, and a record of the night scattered where the reader can find it. She lives in New England with a large, unbothered dog named Otis, and takes her coffee black. The CrimeWord cases are hers, and every one of them can be closed by the person holding the book.
Murder mystery word search: 102 puzzles for adults in 6 cases, including The Last Night at Meridian.
Murder mystery word search: The Daily Flight, a whodunit with 6 cases and 102 puzzles.
