If A drian orders ham, Buford orders pork. Either Adrian or Carter orders ham, but no t both. Buford and Carter do not both order pork. Who could have ordered ham yes terday, pork today?It is a rare event when a book of truly new logical puzzl es is primed, but George Summers has now twice produced such an event. In New Pu zzles in Logical Deduction he created 50 truly new puzzles. With new turns of th ought, new subtleties of inference, he has here created 50 more! Even if you hav e not seen the basic situations before, you have never before had a chance to te st your logic against the precision of scope of these.The puzzles range in d ifficulty from the relatively simple examples at the beginning of the book to ot hers, tricky, complex, and subtle enough to test the expert. Most are set in sto ry form. Some are concerned with establishing identities from minimal clues. Oth ers are based on cryptarithmetic, or the identification of numbers. While an occ asional problem involves algebra, no special knowledge is required for most, no mathematics beyond high school, no training in traditional or symbolic logic. Al l that one need to them is the ability to think clearly and consecutively, and t o pursue the puzzles in the most downright logical way.Among the strongest f eatures of Summers' book is the solutions section, which takes the reader throug h every step and every implication of the solutions. After seeing one solution, you cannot help but test your logic against the next puzzle in the book.
