"I say, Mr. Darrel," he burst out, "there are two murderers!"

"Two!"

"Yes--a man and a woman!"

"A man and a woman!" repeated Darrel thoughtfully. "Who told you that, Mr. Torry?"

"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."
