Fyles drew a deep breath.

“Will you marry me after I have caught the leader of the gang, if he be this man, Bryant? That must be your payment—for being wrong.”

In a moment all Kate’s lightness vanished. She stared at him for some wide-eyed moments. Then, again, all in a moment, she began to laugh.

“Done!” she cried. “I accept, and you accept! It’s a wager!”

But her ready acceptance of his offer for the first time made the police officer doubt his own convictions as to the identity of the head of the gang.

“You are accepting my condition because you believe Bryant is not the man, and so you hope to escape marrying me,” he said almost roughly.

“I accept your condition,” cried Kate staunchly.

Slowly a deep flush mounted to the man’s cheeks and spread over his brow. His eyes lit, and his strong mouth set firmly.

“But you will marry me,” he cried, with sudden force. “Whatever lies behind your condition, Kate, you’ll marry me, as a result of this. The conditions are agreed. I take your wager. I shall get the man Bryant, and he’ll get no mercy from me. He’s stood in my way long enough. I’m going to win out, Kate,” he cried; “I know it, I feel it. Because I want you. I’d go through hell itself to do that. Quick. Tell me. Show me how I can get these people, and I promise you they shan’t escape me this time.”

But Kate displayed no haste. Now that the wager was made she seemed less delighted. After a moment’s thought, however, she gave him the information he required.
