London, 1875. At Lady Cornford’s famous soiree (sugared almonds and tittle-tattle), everyone is gossiping about Henry Ellis Margam’s latest hit, The Widow’s Secret. Only a few people know that one of Lady C’s guests, the enigmatic Bella Wallis, is in fact the best-selling novelist. Bella punishes evil-doers by exposing them as thinly disguised characters in the books she writes under her male pseudonym. Armed with her pen, the handsome Miss Wallis surrounds herself with useful men: the dashing Philip Westland, possibly a government spy; Captain Quigley, Bella's fixer; and his shady assistant, Murch, who can always crack a bone or two when someone needs persuading. Westland comes to Bella with a problem: his best friend, Kennett, is smitten by the heiress Miss Mary Skillane. But Mary’s father, Sir William is ‘an old fraud with a beautiful daughter’ and she has been promised to Robert Judd, a vulgar treasure seeker. Mary is due to inherit the Skillane pearls, currently residing in a red lacquer box in a Cornish bank vault. But the pearls it seems were ill-gotten, and as Bella and her band uncover more of the strange business, a new Henry Ellis Margam novel looks set to be written, if Bella can first side-step her own affairs of the heart, and evade a brutal threat to her life....

Liz McGregor, struggling to bring up her eight-year-old daughter alone, is surprised when her boss asks her to marry him. It is an unromantic proposal, but Liz, beset with difficulties, is tempted to accept it. Then Felix suggests a honeymoon cruise in the Adriatic and Liz's fears are swept away. After eight empty years she is loved - and in love - again. But the past catches up with her and before England's shores are out of sight she is embroiled again with the man who ruined her life before. Doubts about Felix, and fears for her daughter left at home, sap her confidence and judgement. The voyage from Tangier to Nice becomes fraught with danger and is indeed through troubled waters.
