The Jewel that was Ours

The Jewel That Was Ours is the ninth novel in Colin Dexter's Oxford-set detective series.

He looked overweight around the midriff, though nowhere else, and she wondered whether perhaps he drank too much. He looked weary, as if he had been up most of the night conducting his investigations . . .
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 . . .
The Jewel That Was Ours is followed by the tenth Inspector Morse book, The Way Through the Woods.
