October 1888: During the construction of the Metropolitan Police headquarters near Whitehall, which would later become known as Scotland Yard, the remains of a body were found. In September, a severed arm had already been discovered in the muddy bank of the River Thames.

There is another murderer who roams the streets of London in Whitehall, entertaining himself by scattering a poor woman's pieces around Whitehall, like some kind of macabre treasure hunt. The identity of this monster and its unfortunate victim are a mystery, the Whitehall Mystery.
