The Detective’s Casebook

80 Illustrated Whodunit Logic Mysteries

by Heshan Thiwanka

Follow the clues. Test your logic. Find your way through the mystery.

The Detective’s Casebook brings a detective’s atmosphere to a varied collection of puzzles for adults. Search for evidence-themed words, fill number grids, fit words into criss-cross puzzles, decipher coded messages, and trace routes through mazes. Missing objects, suspicious alibis, concealed routes, and evocative locations set the scene for each challenge.

Inside are 100 puzzles: 20 word searches, 20 sudoku, 20 criss-cross puzzles, 20 cryptograms, and 20 mazes. The table of contents groups them under intriguing case-inspired headings, including The Open Drawer, Footprints by Ferns, Library Disturbance, The Brass Key, and The Final Audit. A how-to-use page offers a starting point, and the solutions are at the back when you want to check your work.

Choose the puzzle style that suits your mood, work through a case-inspired theme, or switch between words, numbers, codes, and routes. This collection makes a thoughtful gift for adults who enjoy brain teasers and detective settings—or a satisfying way to take a break and give your mind a fresh challenge.
