Sea Detective

Cal McGill is an Edinburgh-based oceanographer, environmentalist and one-of-a-kind investigator. Using his knowledge of the waves - ocean currents, prevailing winds, shipping records - McGill can track where objects came from or where they've gone. It's a skill that can help solve mysteries ranging from disappearances to murder. Two severed feet wash up on two different islands off the coast of Scotland. Forensics shows that the feet belong to the same body.

Five years ago, 14-year-old Max Wheeler disappeared from Priest's Island, an isolated but bleakly beautiful place on the edge of the Atlantic Ocean. In the close-knit local community, there are no secrets - except what happened to Max. None of the police or private investigations since have shed any light on what happened the night he went missing, presumed dead. But there is one man who is yet to take on the case: The Sea Detective.
