Secrets on the Cote D'Azur

SUSSEX, ENGLAND, 1929.
Mydworth is a sleepy English market town just 50 miles from London. But even in this idyllic spot, crime is never far away...
Luckily the young and adventurous Sir Harry Mortimer has returned to Mydworth from his diplomatic posting in Cairo, with his unconventional American wife, Kat. And between them they are a match for anything - even murder.
SECRETS ON THE COTE D'AZUR
When Harry and Kat head south to the French Riviera, they look forward to dazzling parties, a shimmering sea, and wonderful food. But once they step off the legendary Paris-Nice train, Le Train Bleu, things start to be anything but restful.

Asked to assist in a dangerous case of blackmail - they soon find that the streets and alleyways of the Cote d'Azur hide not only cafes and bistros... but also secrets and danger of a most deadly sort.
