Blanchard Twins

Meet the Blanchard twins: Rose is practical, sharp, and protective. Specialty: manta rays. Finn is too sweet and kind for his own good. Specialty: sharks. Rose and Finn are looking for sharks on the sea bed. When they return to the Dauphin they make a terrible discovery: their colleague has been murdered on the ice - with a harpoon that should never have been there. Everyone else on the luxury cruise ship - the wealthy passengers, the researchers hard at work, the tight-knit crew and their strangely calm Captain - were all aboard at the time, so they are all under suspicion.

Scientist Finn Blanchard is trying not to think about murder. The university administrator Nina Hussar may have fallen to her death down stairs she'd used for years, but the only mystery Finn wants to investigate is whether there's a shark in the local lake. But when a professor's sudden death unearths cryptic clues to a missing Shakespeare play, Finn is forced to admit his research isn't the fishiest part of university life. After all, as his detective ex-boyfriend says, there's nothing more suspicious than a fall down some stairs.
