"Oh, all right, if you are going to get mad about it," he said and stepped aside peering intently at the side of the car on which Dixie was seated. Plainly written there were these words:

"Will send message boy by tonight. Watch hotel alley."

As the machine disappeared in the distance the motorcycle policeman raised his goggles and laughed. It was Harrison Grant.

But Heinric von Lertz did not know. Defying the rules of the road he was speeding toward the hotel, his good humor of a few minutes before dissipated by the dispute with Grant. Suddenly the speed of the car slackened but a few doors from the hotel.

"Do you know those two men?" demanded Von Lertz.

Dixie Mason turned in the direction he pointed. Baroness Verbecht and Madam Stephan were aiding Cavanaugh and Stewart of the Secret Service, both of them apparently intoxicated, into a taxicab standing at the curb. Stewart noticed Von Lertz pointing at them and waved a maudlin salute as he ordered the chauffeur to drive to a roadhouse on the outskirts of Buffalo in a thick loud voice.

"Do I know them?" retorted Dixie. "Do you know Harrison Grant?"

"Yes, the dog," muttered Von Lertz.

"Those are his two best men."

"Good," said Von Lertz, smiling happily, "I will commend Verbecht and Stephan in my report."
