Blinders, the policeman on duty at the entrance of the square, gave evidence that he had been on duty there all night, and that although many servants and owners of houses belonging to the square had passed in from their Christmas marketings, yet no stranger had entered. The policeman knew every one, even to the errand-boys of the neighbourhood, who brought parcels of Christmas goods, and in many cases had exchanged greetings with the passers-by; but he was prepared to swear, and, in fact, did swear at the inquest, that no stranger either came into or went out of Geneva Square. Also he deposed that when the traffic died away after midnight he had walked round the square, and had looked at every window, including that of No. 13, and had tried every door, also including that of No. 13, only to find that all was safe. Blinders declared on oath that he had not on Christmas Eve the slightest suspicion of the horrid tragedy which had taken place in the Silent House during the time he was on duty. When the police took possession of the body and mansion, search was made in bedroom and sitting-room for papers likely to throw light on the identity of the victim, but in vain. No letters or telegrams, or even writing of any kind, could be discovered; there was no name in the dead man's books, no mark on his clothes, no initials on his linen. The landlord of the house declared that the deceased had hired the mansion six months before, but had given no references, and as the landlord was glad to let the haunted No. 13 on any terms, he had not insisted upon having them. The deceased, said the landlord, had paid a month's rent in advance in ready money, and at the end of every month he had discharged his liability in the same way. He gave neither cheque nor notes, but paid always in gold; and beyond the fact that he called himself Mark Berwin, the landlord knew nothing about him. The firm who had furnished the rooms made almost the same report, quite as meagre and unsatisfactory. Mr. Berwin--so the deceased had given his name--had ordered the furniture, and had paid for it in gold. Altogether, in spite of every effort, the police were obliged to declare themselves beaten. They could not find out the name of the victim, and therefore were unable to learn his past life, or trace thereby if he had an enemy likely to harm him. Beyond the report given by Lucian of his conversation with the man, which showed that Berwin certainly had some enemy whom he dreaded, there was nothing discovered to show reason for the committal of the crime. Berwin--so called--was dead; he was buried under his assumed name, and there, so far as the obtainable evidence went, was an end to the strange tenant of the Silent House. Gordon Link, the detective charged with the conduct of the case, confessed as much to Denzil. "I do not see the slightest chance of tracing Berwin's past," said he to the barrister. "We are as ignorant about him as we are of the name of the assassin."
