January, 1554. Light-fingered Jack Blackjack knows he's not going to have a good day when he wakes with a sore head next to a dead body in a tavern's yard. That would be bad enough - but when he discovers what's in the dead man's purse, the one he'd stolen, his day is set to get much worse. The purse explains why the mysterious man with the broad-brimmed hat wants to catch him. But so does the Lord Chancellor, as does the enigmatic Henry. In fact, almost everyone seems to be after Jack Blackjack.

If it weren't for the rebel army marching on London determined to remove Queen Mary from her throne and install Lady Jane Grey in her place, Jack could leave the city - but with the bridge blocked and every gate manned, there's no escape.

Instead he must try to work out who killed the man in the yard, and why. But it won't be easy as the rebel army comes ever closer and the death toll mounts ...
