It s not elementary, but you will need Holmes s famed powers of deduction to solve these crafty puzzles. Here s how it goes: at the end of each conundrum, you ll find at least one condition and sometimes more that the solution must meet. For example, here s the first, relatively simple problem:
Mr. Scott, his sister, his son, and his daughter are tennis players.
- The best player s twin and the worst player are of the opposite sex.
- The best player and the worst player are the same age.
Which one of the four is the best player?
Did you figure out that Mr. Scott s sister had to be the same age as his children?
A few of the puzzles demand a basic knowledge of algebra, and others feature drawings or diagrams.
