How old is Mary if she is twice as old as John was when they first met? Henry Dudeney, the master puzzle-maker, filled this book with hundreds of such teasers: money puzzles, clock puzzles, kinship riddles, and problems of speed and digits. Fiendish, elegant, and fully solved at the back. Sharpen your wits on a genius's games.

Every copy includes a printable PDF edition, a beautifully typeset book you can print, mark up in the margins, and keep on your shelf. Yours the moment you own it.
