"The third, cabman," replied the detective. "Main is his name. I found him along with Henry and Bike on the cab-stand near Mortality-lane." "Had you any difficulty in making him speak?" "No, not the least. He was quite willing to give information and assist the police in every way. Why do you suggest a difficulty?" "Why," said Darrel, "if this man and woman were actually the assassins it is possible they might have bribed Main to silence." "And hereby roused his suspicions," retorted Torry sharply. "Nothing of the sort. Main did not know what lay down the lane, so there was no need for the pair to purchase his silence." "They came out of Mortality-lane?" "Yes. Main says that after the other two cabs drove away, he almost decided to go home himself as he despaired of getting a fare at so late an hour. However, on the chance he waited for twenty minutes or so, and his patience was rewarded shortly before one o'clock. A man and a woman came out of Mortality-lane, and got into the cab which drove off." "Then it left just before our cabs came back?" "No doubt; the assassins ran the thing very fine. Well the woman told Main to drive to Northumberland-avenue near the theatre. There the two alighted and dismissed the cab." "What did they do next? I suppose Main noticed in which direction they went?" "No, indeed," replied Mr. Torry with a vexed air. "He got his money and went straight home, leaving the man and woman standing on the pavement in front of the Avenue Theatre." "What route did he take from Mortality-lane to Northumberland-avenue?" "Down Arundel-street and along the Embankment," replied Torry promptly. "I suppose," said Darrel reflectively, "that he did not notice any one near Cleopatra's Needle as he drove along? "No, I asked him if he did, but he declared that he was too much taken up with managing his horse, which was rather unruly, to cast a look to right or left. He drove to his destination, then returned home by going up the Avenue." "Can he describe the pair?" "H'm!" said Torry dubiously, "not very clearly. The woman was tall, fair-haired, dressed in black and veiled. I know all that, as I have seen her dead body and dress. The man was not so tall as the woman, with a black beard, and wore a soft hat and a long overcoat almost to his heels. He was slender and silent, leaving the woman to give the directions and pay the fare." "Were they agitated?" "The man seemed more agitated than the woman." "Perhaps he killed Mr. Grent." "Perhaps he did; we have no evidence to shew who struck the blow. But who is Mr. Grent?" "The dead man. He is, or rather was, Mr. Jesse Grent, the banker."
