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.

But there is one man who is yet to take on the case: The Sea Detective.
