THE NEW EXETER BOOK OF RIDDLES. Edited by Lawrence Sail. Enitharmon pound;7.95.
In Roberto Benigni's recent Oscar-winning film Life is Beautiful, the exuberant hero wins the friendship of a Nazi doctor by solving riddles with him. And when Gollum meets Tolkien's hobbit, Bilbo Baggins, they compete in riddles.

Philip Gross's riddle for DNA is a perfect example of the alchemy that makes one thing mean another, leaving both of them changed forever by the contact: "Two spiral stairs we climb to bed together Each step creaks a different who-goes-there."
Sophie Hannah's riddle of a single bed in a hotel room chooses instead to bring the object into sharper focus.
These riddles are now among my favourite poems by these writers. That may not be the case for every poem in the book, but this will be a companion that I will recommend again and again.
