"That," said Harkness; and he produced a worn heel torn from its sole and uppers.

"Exactly," said Rigden, nodding.

The sergeant sprang from the bed.

"Have you struck his tracks?"

"I won't say that," said Rigden. "All I undertake is to show you a distinct track with no left heel to it all down the line. No, I won't shake hands on it. It may lead to nothing."
