They preferred to stop and see the end of the inquest.
Skillful and experienced detectives were summoned by telegraph from Scotland Yard, London, and arrived at the castle about midnight.
The house was placed in charge of the police while the investigation was pending.
But the materials for the formation of a decided verdict seemed very meagre.
A careful examination of the body showed that the banker had been killed by one mortal blow inflicted by a blunt and heavy instrument that had crushed in the skull.

The instrument was searched for, and soon found in a small but very heavy bronze statuette of Somnes that used to stand on the bedroom mantel-piece; but was now picked up from the carpet, crusted with blood and gray hair.

But the miscreant who had held that deadly weapon, and dealt that mortal blow, could not be detected.
Investigation further brought to light that an extensive robbery had been committed.

From the banker's person his diamond-studded gold watch, chain, and seals, his gold snuff-box, set with emeralds, a heavy cornelian seal ring set in gold, and his diamond studs and sleeve buttons were taken.

A patent safe, which stood in his room, and contained valuable documents as well as a large amount of money, had been broken open, the documents scattered, and the money carried off.
Yet no trace of the robber could be found.
The broken safe was the only piece of "professional" burglary to be seen anywhere about the house.
