25 hand-picked riddles

Riddles for Adults

The children have gone to bed, the fire is low, and there is something agreeable in your glass. Now we may have the other sort of riddle.

These twenty-five are not about combs and kites. They are about time and truth, lies and jealousy, grief and habit; the things one only learns to recognise after a few decades of living. Others are plain trickery: questions that sound like arithmetic or geography and turn out to be nothing of the kind. I recommend reading those very slowly, for the trap is usually in the wording.

They make a fine game for a dinner table. Read one out, let the arguments begin, and refuse to reveal the answer until somebody has changed their mind at least twice.

Gerald, my crow, is of the view that riddles for adults ought to involve more shiny objects. I have told him that is a matter for his own collection, and he has gone off to sulk on the battlements.
