Features: The puzzles in this book are all written as short mysteries like "Whodunit." Each puzzle provides several clues and asks the reader, or rather the "detective," to identify which among different objects is the one being sought (or, to continue the analogy, which among the suspects is the real culprit). In these puzzles, some genuinely require you to identify a culprit, but the vast majority only involve basically law-abiding citizens or purely numerical elements. The general method for solving these puzzles is: at the end of each puzzle, the question states a condition that the object being sought must satisfy. For example, "Of the four baseball teams—Cougars, Reds, Pumas, or Kittens—which team won the championship?" defines "won the championship" as a condition. The clues in the puzzle also explicitly or implicitly state the conditions that each "suspect" must meet. The detective's task is to discover all the conditions and then determine which—and only one—"suspect" can satisfy the conditions stated in the question. The puzzles are arranged in order of increasing difficulty, so if a reader starts with the puzzle and progresses sequentially, they will find that they are able to solve those that were originally considered too difficult. To help readers who get stuck, each puzzle comes with a "Hint"—listed upside down at the bottom of the page—to guide their thinking in the right direction. Few books on logical puzzles have been published, but Mr. George Summers has made such a contribution. There are a total of 50 carefully designed logical puzzles in the book, arranged from easy to difficult. The most challenging puzzles are even likely to stump experts. You may not have had the chance to test your logical reasoning skills yet, and now is a great opportunity—don't miss it!
