Kitty Underhay is drowning...in murder.

Kitty Underhay hopes for plain sailing as she caters a 21st birthday party for the chief constable’s daughter aboard a luxury paddle steamer. So her heart sinks when she learns that the man her fiancé Matthew has been tailing on orders from Whitehall, Gunther Freiburg, is aboard. And she’s even more horrified when she steps below deck to discover Gunther, dead in the engine room. One of the chief constable’s party must be responsible for his demise, but who, and why?

And the evening is on course for further disaster. As the lights go out around the candlelit cake, a terrible scream rings out over the merry hubbub. A priceless diamond necklace has been snatched from around the birthday girl’s neck.... Something fishy is going on, but is this the work of the same sailing assassin, or is it a red herring?

With the local inspector in deep water having to investigate his own boss, Kitty and Matt dive in to help. But when Kitty’s eavesdropping puts her in mortal danger, will everything turn out shipshape, or will it be her turn to go swimming with the fishes?

A totally cozy, absolutely gripping historical murder mystery for fans of Agatha Christie, T.E. Kinsey, and Lee Strauss.
