The Baseball Mysteries

The Baseball Mysteries: Challenging Puzzles for Logical Detectives is a book of baseball puzzles, logical baseball puzzles. To jump in, all you need is logic and a casual fan's knowledge of the game. The puzzles are solved by reasoning from the rules of the game and a few facts.

The logic in the puzzles is like legal reasoning. A solution must argue from evidence (the facts) and law (the rules). Unlike legal arguments, however, a solution must reach an unassailable conclusion.

There are many puzzle books. But there's nothing remotely like this book. The puzzles here, while rigorously deductive, are firmly attached to actual events, to struggles that are reported in the papers every day.

The puzzles offer a unique and scintillating connection between abstract logic and gritty reality.

Actually, this book offers the reader an unlimited number of puzzles. Once you've solved a few of the challenges here, every boxscore you see in the papers or online is a new puzzle! It can be anywhere from simple, to complex, to impossible.

• For anyone who enjoys logical puzzles
• For anyone interested in legal reasoning
• For anyone who loves the game of baseball.
