A strange container is found on the London docks, and its contents point to murder

The cask from Paris is bigger than the rest, its sides reinforced to hold the extraordinary weight within. As the longshoremen are bringing it onto the London docks, the cask slips, cracks, and spills some of its treasure: a wealth of gold sovereigns. As the workmen cram the spilled gold into their pockets, an official digs through the opened box, which is supposed to contain a statue. Beneath the gold he finds a woman’s hand—as cold as marble, but made of flesh.

He reports the body to his superiors, but when he returns, the cask has vanished. The case is given to Inspector Burnley, a methodical detective of Scotland Yard, who will confront a baffling array of clues and red herrings, alibis and outright lies as he attempts to identify the woman in the cask—and catch the man who killed her.
