The Jewel That Was Ours (Inspector Morse, #9)

For Oxford, the arrival of twenty-seven American tourists is nothing out of the ordinary... until one of their number is found dead in Room 310 at the Randolph hotel.
It looks like a sudden—and tragic—accident. Only Chief Inspector Morse appears not to overlook the simultaneous theft of a jewel-encrusted antique from the victim's handbag...
Then, two days later, a naked and battered corpse is dragged from the River Cherwell.
A coincidence? Maybe. But this time Morse is determined to prove the link...
