"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?
