Elle est Morte, Mate! (She is Dead, Mate!) - by Allan McFadden (Paperback)

Book Synopsis

Mary-Anne Walton wasn't coming back. Caught up in the explosive scandal destroying the reputation of her boss, international movie producer Harold Kempenski, she'd slipped off the stern of The Blue Dahlia. Her body was never found. I was rocked by her disappearance because I knew she was innocent.
I'm Dougay Roberre, an Australian living on the French Riviera, and after Mary-Anne's demise, friends suggested I get away, to go to Gallipoli on an Australian pilgrimage; however, when there, they didn't advise me to become entangled with a gorgeous Brazilian-American woman who seemed to have stepped from the sands of Copacabana Beach!
Before I could enjoy Türkiye, there were a few things to be done. I had to assist a young woman in love escape the overbearing clutches of her obsessive brother; track down a stolen jade chess set; and try not get involved in the aftermath of a blaze in a car yard.
All in all, nothing out of the ordinary for me, n'est ce pas?
