The Puzzle Murders: Assorted Puzzles

The Puzzle Murders: Assorted Puzzle Book, by Igloo Books.

There’s a killer on the loose in Graven End, and it’s up to you to help Detective Kate McCrawley catch them. There have been six brutal murders, each one completely different, except for the puzzles the killer leaves behind at each crime scene. Only your ability to crack crosswords, solve sudoku, and untangle fiendish puzzles stands between the killer and their seventh victim.
