"When Santa arrives at a child's house on Christmas Eve, does he go down the chimney feetfirst or headfirst? What if he gets stuck? What if there's no chimney? Maybe he slides under the door, as thin as a piece of paper? Or is it possible he pours himself through the faucet? What happens once he's inside?

In 1989 someone is threatening to steal the crown jewels, so the Queen of England summons Mac B. to England to protect them--and when they are stolen from a locked dungeon cell, where Mac and Holcroft, one of the warders, are supposed to be guarding them, it is up to Mac to figure out how they were stolen, and whether the thief is the descendant of an Irish soldier-of-fortune who tried to steal them in 1671, or someone else entirely.
