“I don’t know anything about that, sir,” answered Heath. “But I know that European crooks use those signs.”

“Oh, doubtless. I ran across a number of ’em when I was looking up the emblematic language of the gypsies. A fascinatin’ study.” Vance seemed uninterested in Ada’s discovery.

“Have you this paper with you, Miss Greene?” asked Markham.

The girl was embarrassed and shook her head.

“I’m so sorry,” she apologized. “I didn’t think it was important. Should I have brought it?”

“Did you destroy it?” Heath put the question excitedly.

“Oh, I have it safely. I put it away. . . .”

“We gotta have that paper, Mr. Markham.” The Sergeant had risen and come toward the District Attorney’s desk. “It may be just the lead we’re looking for.”

“If you really want it so badly,” said Ada, “I can phone Rex to bring it with him. He’ll know where to find it if I explain.”

“Right! That’ll save me a trip.” Heath nodded to Markham. “Try to catch him before he leaves, sir.”
