“He’s followed us--let’s get out of this quick. Give me the envelope.” Lambaire went white. “I--I gave it to you,” he stammered. “You liar!” Whitey was in a white heat of fury. “You gave me nothin’! Give me the envelope.” “I gave it to you, Whitey,” Lambaire almost whimpered. “As soon as you left the room you came back and asked for it.” “Did I come in--quick.” “No, no,” The agitation of the big man was pitiable. “You put in your hand and whispered----” “Amber!” howled the other. He broke with a torrent of curses. “Come on, you fool, he can’t have got far.” He flew down the stairs, followed by Lambaire. The hall was deserted, the door had been left ajar. “There he is!” By the light of a street lamp they saw the fleeing figure and started off in pursuit. There were few people in sight when a man in his stockinged feet came swiftly from Northumberland Avenue to the Embankment. “Stop, thief!” bawled Whitey. The car was further along the Embankment than he had intended it to be, but it was within easy sprinting distance. “Stop, thief!” shouted Whitey again. Amber had gained the car when a policeman appeared from nowhere. “Hold hard,” said the man and grasped Amber’s arm. The two pursuers were up to them in an instant. “That man has stolen something belonging to me,” said Whitey, his voice unsteady from his exertions. “You are entirely mistaken.” Amber was more polite and less perturbed than most detected thieves. “Search him, constable--search him!” roused Whitey. Amber laughed. “My dear man, the policeman cannot search me in the street. Haven’t you an elementary knowledge of the law?” A little crowd of night wanderers had collected like magic. More important fact, two other policemen were hurrying towards the group. All this Amber saw and smiled internally, for things had fallen out as he had planned. “You charge this man,” the constable was saying. “I want my property back,” fumed Whitey, “he’s a thief: look at him! He’s in his stockinged feet! Give me the envelope you stole....” The two policemen who had arrived elbowed their way through the little crowd, and suddenly Whitey felt sick--ill. “I agree to go to the station,” said Amber smoothly. “I, in turn, accuse these men of burglary.” “Take him off,” said Whitey, “my friend and I will follow and charge him.” “We’ll take the car,” said Amber, “but I insist upon these two men accompanying us.” Here was a situation which Whitey had not foreseen. They were caught in a trap unless a miracle delivered them. “We will return to our hotel and get our coats,” said Whitey with an air of indifference. The policeman hesitated, for the request was a reasonable one. “One of you chaps go back with these gentlemen,” he said, “and you,” to Amber, “had better come along with me. It seems to me I know you.” “I dare say,” said Amber as he stepped into the car, “and if those two men get away from your bovine friends you will know me much better than you ever wish to know me.”
