August, 1558. As London is bustling with growing trade from foreign lands, and Queen Mary's health is once again a hot topic, Jack Blackjack has much to keep him busy. And that's before his new tenant - a Dutch merchant - disappears under a cloud of suspicion, quickly presumed murdered, and Jack's latest female companion's body is found mere streets from her dwelling place. People around Jack keep inconveniently getting murdered, and he seems to be the most likely culprit! With both the authorities and the unsavoury echelons of London on his tail, nowhere is safe for Jack to hide. He must go about proving his innocence - and uncovering the mirky truth - while ensuring he doesn't find himself dancing the Tyburn jig!
