A corpse in a gilded cage

Perce Spender, a working-class Londoner, is unexpectedly transformed into the twelfth Earl of Ellesmere when a distant relative dies. But he would rather be warming a bar stool in his local pub, and he's taken up residence at Chetton Hall only until arrangements can be made to sell it. Getting rid of the family estate displeases at least one of Perce's greedy offspring, however, and on the morning after a family party the new Earl is found dead. The Chief Constable's plethora of suspects is not the social-register list he was anticipating--one of Perce's sons is now in jail, one ought to be, one daughter is a bit too curious about the will, and daughter-in-law Dixie, now the new Countess of Ellesmere, has been keeping company with a small-time crook.
