"There he is," he said.
Farrington looked. There was no mistaking Poltavo, but who the other man was, an old man doubled with age, his white beard floating in the wind, Farrington could not say; he could only conjecture.
Dr. Fall, searching the downs with another telescope, was equally in the dark.
"This is the intermediary," said Farrington at last.
They watched the meeting, saw the exchange of the letters, and Farrington uttered a curse. Then suddenly he saw the other leap upon Poltavo and witnessed the brief struggle on the ground. Saw the glitter of handcuffs and turned with a white face to the doctor.
"My God!" he whispered. "Trapped!"
For the space of a few seconds they looked one at the other.
"Will he betray us?" asked Farrington, voicing the unspoken thoughts of Fall.
"He will betray us as much as he can," said the other. "We must watch and see what happens. If he takes him into town, we are lost."
