Got an Imponderable? Want to Win a Book?

My collaborators are readers, who send in the Imponderables, and help track down the answers to mysteries that I'm having a hard time solving. Want to join the crusade?

Send in an Imponderable. Or eight. If you are the first to send in an Imponderable we publish, you'll receive an acknowledgment along with your free, autographed copy of the book in which it appears.
