Then Muggs dashed out to the street again, sprang into the roadster, started the engine, whirled the big machine around, and pursued the taxicab.

"This is tough luck!" Muggs told himself. "It's a cinch that Landers knows this car. He'll spot it in a minute, if we get out of the heavy traffic! I wish I had the boss along!"

The taxicab did not make good speed through the traffic, and Muggs remained about a third of a block behind it. After a time it turned into a cross street, and presently stopped before an exclusive hotel. Muggs swung the roadster to the curb. He saw Landers get out, pay the chauffeur, and disappear into the hotel.

Muggs was out of the car instantly, and hurrying forward. He approached the entrance, and glanced in. Landers had not stopped at the desk, but had gone directly to an elevator. That meant that he was a guest, or a frequent visitor.

When the elevator came down again, Muggs hurried over and spoke to the boy.

"The gent that just rode up with you——" he began.

"Mr. Smith?"

"Maybe his name's Smith—I don't know. I just wanted to find out where he went—got a message for him—phoned it from the office over there."

"He comes here to visit Miss Whaley and her elder sister," the boy explained. "You just ring up No. 256, and I guess you can get him."

Muggs went across the lobby and into a telephone booth. But he did not call room 256. He called Verbeck at Miss Wendell's apartment, and got him on the wire.
