Another Lovejoy Mystery

I just finished Firefly Gadroon.  Lovejoy is forced into finding and rescuing a cache of stolen antiques in the North Sea before they are shipped off to Europe.  Will he succeed?  Can he rescue these prizes?  Would he give them to their rightful owners?  Can he manage all this, save his skin, and avoid killing the bad guys? Oh, and what is a gadroon, anyway?
