Victor Canning: Doubled in Diamonds (UK 2021)

From the Publisher:
The high-stakes second novel in the classic Rex Carver mysteries.
Rex Carver, suave 1960s London PI, has a missing person to find - one who doesn't want to be found.

When Rex Carver is taken on by a solicitor's firm to trace the sole beneficiary, one Arthur Finch, of an estate worth £6,000, he barely considers the job worth going out into the freezing weather for.

But there is far more ice involved than Carver could have imagined. When he connects the seemingly innocuous yet hard-to-find Finch with a Hatton Garden diamond heist, he books the first flight to Finch's bolthole in Ireland, determined to smoke him out...

The Bond of private investigators returns in another thrilling adventure, perfect for fans of Alistair MacLean and Ian Fleming.

Victor Canning: Doubled in Diamonds (USA ca. 1978)

From the Publisher:
That he was dealing with people who were about to trade $3,000,000 in stolen diamonds for heroin and opium didn't make Rex Carver very happy. That two of those people were twin Chinese sisters didn't make things easier, since one of them had just tried to kill him. Then the problems began: the twins were agents of the People's Republic of China.
