"Where's Mellor?" asked Frank, suddenly.
"I don't know."
"Didn't he start out with you?"
"Yes, but we didn't keep together long."
"Where did he go?"
"We separated at the corner of Thirty-second Street and Broadway. I was for going down Broadway, but he said that he wanted to see something of the Tenderloin district."
"The Tenderloin!" exclaimed Frank, with a groan.
Instinctively he hurried his steps.
"Hasn't Mellor turned up yet?" asked Higgins, hurrying along with him.
"No, and unless he's more careful than you were there's no telling what mischief he may have got into."
