Phillip Youngman Carter: Mr Campion's Falcon (USA 2014)

From the Publisher:
"The fictional career of Albert Campion is in excellent hands." -- New York Times
This was the second of two "Albert Campion" novels written by Margery Allingham's husband, Phillip Youngman Carter, after Allingham's death. It was originally published in 1971, an astonishing 42 years after Campion made his debut in Allingham's The Crime at Black Dudley. Mr. Campion's final adventure points (like so many good mysteries) to the past, as first an archeologist is murdered and then a geologist disappears. The latter has a motley crew of friends, all ham-handedly eager to "help" Mr. Campion with his inquiries, and there's also a supremely dastardly villain on hand. It's a pity to say farewell to the estimable Albert, but he leaves on a high note indeed.

Youngman Carter: Mr Campion's Falcon (UK 1973)

From the Publisher:
Matthew James Matthew is a famous geologist. What's more, he's a human divining-rod where the riches of the earth are concerned. So it's not surprising that his irresponsible behaviour stirs up a nest of greedy hornets.

Albert Campion smokes out the industrial spies, gently moralizing and nervelessly bluffing as the situation demands. His 'falcon' is disguised among the remains of a Roman ship (fourth century A.D.), but it is a 'nice dirty little twentieth-century scandal' which he eventually unearths.
