It's black-market–riddled England, and MI5 has pushed cat burglar and jewel thief Jethro out onto the rooftops of London—again—in defense of the Realm. Ever looming in the background are the twin spectres of the growing communist menace and a resurgence of fascism. Things turn decidedly deadly when Jethro stumbles across a Royal cover-up and an extreme right-wing plot to topple Britain's new Labour Government. He must pull off a very dodgy and dangerous caper, the success or failure of which could save England from going to the dogs or spell curtains for Jethro.
