Bitte recht freundlich, es wird geschossen

$250,000 worth of jewels were stolen from Lady Hamilton's safe three years ago. Only one person could have committed the burglary: Joe Baxter. As "Safecracker Joe" he is known and notorious in the London underworld. Where is old Baxter hiding his loot? So far, of course, the jewelry has never appeared again. The American insurance company concerned puts one of its most capable agents, Barney Kershaw, on the trail of the alleged perpetrator. Kendall and Donovan, two crooks from relevant London circles, are also interested in the jewels.
