If you are looking for the ultimate in logic puzzles that require pure deductive reasoning then this is the comprehensive collection for you. Even if you are new to logic puzzles, the startlingly simple instructions and crystal clear grids provide an easy introduction to this totally absorbing and intellectually stimulating pastime. Every puzzle is a whodunnit in its purest form with each grid being a scene of crime, each digit representing a potential suspect and each clue providing vital forensic evidence.

By determining means, motive and opportunity as well as moving from the possible to the probable to the provable, every 'crime' contained herein can be solved by using pure intellect and reason: all you need is the perception and perseverance to identify and pursue the right line of enquiry.

Choose from any of the ten, or all ten, and see how you stand up against Charles Barry Townsend -- "the Professor of Perplexing Puzzles".
