"This is Merriwell," explained Frank. "Is there anything that will prevent you from giving me your services to-night?"

"Well, nothing that I know of, if the business is important; but I'll have to know what's doing in order to make it right here."

"I don't like to explain over the phone," said Frank. "If you can wait, I'll jump into a cab and come right down to tell you all about it."

"I'll wait," was the assurance.

Merry lost no time in taking a cab for police headquarters, where he found the plain-clothes man waiting for him.

"Bronson," said Merriwell, "I've found Felipe Jalisco."

"Have you? Well, it will give me some satisfaction to again get my hands on that slippery chap."

"But I believe I have found something far more important. You know I told you that I was convinced of foul play in the Watson Scott affair, and also in the seeming accident that happened to Warren Hatch."

"Which seems entirely improbable to me."

"I think I'll be able to convince you to-night that I was not mistaken in either case. Further than that, I hope to place within your grasp the wretch who drugged Scott and bribed Hatch's chauffeur to bring about that accident."
