"We can't do it to-night," announced Sage with decision.
Colonel Walton shook his head.
"He must take the risk until the morning," continued Sage. "You'll be here until it's all through?" he interrogated.
Colonel Walton nodded. When thoughtful he was more than usually sparing of words.
"About the reward?" he interrogated, as Sage rose and moved towards the door.
"We'll withdraw it in to-morrow evening's papers," was the response, "if you agree."
Again Colonel Walton nodded, and Malcolm Sage went out, bent on reminding Scotland Yard of his existence.
