Mr J. G. Reeder, super-sleuth extraordinaire, is now working for the Public Prosecutor’s bureau and investigating the case of Sir James Tithermite’s wife who fell overboard from the Channel steamer crossing to Calais. There’s something very fishy about this business. Miss Margaret doesn’t like him, for she knows he’s after her money.

The Treasure Hunt is Casefile Number two which is also included in Casefile Numbers one, two, and three from The Mind of Mr J G Reeder by Edgar Wallace.
