"We'll see whether he'll come or not!" Landers said. "If the telephone is not out of commission——"

During the hot summer months, the roof was used as a garden. There was a little building in one corner of it that was used as a refreshment stand, and there always was a telephone there.

Verbeck knew that Landers was rushing across the roof to the building. He heard him smash against the frail door, heard it crash in. The women, it was evident, remained near the door leading to the stairs that went below.

Leaving the shadow of the chimney, Verbeck crept forward toward the little structure where Landers had gone to telephone. He hoped to catch the Black Star's lieutenant at a disadvantage and subdue him. He was much interested, too, in what Landers' telephone message might be, and to whom it would be sent.

Without a sound, Verbeck crossed the roof and came to the side of the little building. Landers had flashed an electric torch, and was taking the telephone from beneath the counter. Verbeck saw him take down the receiver.
