On an amateur dig in Israel, two students discover what appears to be the femur of a very large humanoid, and there's compelling evidence to suggest that it's the thigh bone of the Biblical giant, Goliath. Back in New York, they head into the subway carrying the carefully wrapped bone when a hitman attempts to kill them. Hammer comes to their rescue. It is only the beginning of their troubles. Some people will stop at nothing to get their hands on the precious item, each for their own nefarious reasons. Hammer and his loyal assistant Velda assure once again that the decent guys triumph in this cracking new thriller from an acknowledged master of the genre.
