I rushed over to him, and by the light of the street-lamp saw that blood was flowing from a great wound in his skull. Then, in a moment, Benham was beside me, and the constable and sergeant came running back, being joined by a second constable.

Meanwhile Vernon, as well as the two thieves, had disappeared.

The man attacked was senseless. The wound in his head was a terrible one, apparently inflicted by a jemmy or life-preserver; so quickly an ambulance was sent for, and the poor fellow was swiftly conveyed, apparently in a dying condition, to the Middlesex Hospital.

At first the police regarded me with some suspicion, but when Benham explained who he was, and that our attention had been attracted by "something wrong," they were satisfied. We, however, went round to the police-station and there made a statement that, in passing we had seen two men—whom we described—enter the premises with a key, and as they did not emerge, we waited, until we saw them escape, followed by the injured watchman.

Then—it being about half-past three in the morning—we went back to the jeweller's, and there found the place in a state of great disorder. At the back of the window pieces of black linen had been suspended, in order to shut out the light from the small gratings in the shutters, and, in what they had believed to be perfect security, the thieves, wearing gloves, had forced open several show-cases and packed their most valuable contents in a cotton bag ready for removal. The big safe, one by a well-known maker, stood open, and the various valuable articles it contained had been pulled roughly out, examined, and placed aside ready to be packed up, together with a bag containing about one hundred sovereigns, and a small packet of banknotes.

On the floor lay a beautiful pearl collar, while everywhere empty cases were strewn about. Yet, as far as could be ascertained from the manager, who had come up hastily in a taxi, nothing had been taken.

Detectives came and began a thorough examination of the premises, and the damage done.

They were looking for finger-prints, but it was not likely that practised experts such as Jules Jeanjean and his companion would risk detection by leaving any.

I kept my knowledge to myself, and returned, weary and hungry, to my rooms, Benham accompanying me, and there we discussed our plans for the morrow.
