The cases of Special Investigator "Jigsaw" John St. John of the LAPD.

No one was better at solving puzzles than Los Angeles police detective John St. John. That's why he was handed the nickname "Jigsaw", as his amazing deductive abilities and interpretation of clues led him to solve a series of baffling murders. Sam Donner was St. John's younger partner, and Maggie was an elementary school teacher whom Jigsaw dated.—Marty McKee <[email protected]>
