Larry swung around, ready to meet his opponent when he should come back to the attack. At that instant a window, in a house across the street, opened, and a voice the young reporter knew was Grace's called:
"Larry! Larry! Come here!"
He started to run across the thoroughfare, but, as he did so, he saw another man emerge from behind a tree, next to the one where Sullivan had been concealed. And, as the light from an arc lamp gleamed on this man's face, Larry saw it was that of Mah Retto.
The young reporter paused, undecided what to do. Across the street he could see Grace in the raised window, waiting for him—for what he did not know. But, even as he looked at her, he saw Retto running off down the street. In an instant Larry's mind was made up. He took after Retto as fast as he could run.
CHAPTER XXII
GRACE IS SUSPICIOUS
Retto headed for Central Park, and as Larry saw him pass the entrance he realized that it was going to be as hard to follow the man as though he had disappeared in the midst of a crowd, especially since the park was not well lighted.
"But I've got to follow him," thought Larry. "It's my best chance. I must find out where he has moved to. I wonder what Grace wanted? And I wonder what Sullivan's game was? My, but the questions are coming too thick for me. I'll have to get an assistant."
