Early work follows Ashe Marson into the drafty halls of Blandings Castle, where he will try to make "something new" of his life by purloining a rare Egyptian scarab — all for the best motives, of course. The resultant hilarious romp through a stately English country home also introduces other characters who recur throughout the Blandings Castle Saga.
