“Oh, send the girls out to tea,” said Bell. “No. I can’t do that. I had rather come with you, Mr. Superintendent. I would rather indeed.” “Come on then.” Mr. Witt, who was shaking with nervous fear, caught up his hat and coat. The farther door of the room was flung open. Two pistol shots were fired. As Reggie sprang at the door it was slammed in his face and locked. Mr. Witt went down in a heap. Bell dashed through the outer office into the corridor. Reggie knelt by Mr. Witt. “Kuyper,” Mr. Witt gasped. “Kuyper.” “I know. I know. We’ll get him yet. Where’s he gone?” “His yacht,” Mr. Witt gasped. “Yacht at Gravesend. He had it ready.” He groaned and writhed. He was hit in the shoulder and stomach. Reggie did what he could for the man, and went to the telephone. He had finished demanding an ambulance when Bell came back breathless, with policemen in uniform at his heels. “The swine,” Bell gasped. “He’s off, sir. Must have gone down the other staircase into Bull Court. We had a man there but he wouldn’t know there was anything up, he’d only follow. Pray God he don’t lose him. They lost him last night.” “Send these girls away,” said Mr. Fortune. “Let the constables keep the door. I want to use the telephone.” And when the ambulance had come and taken Mr. Witt, happily unconscious at last, to hospital, he was still talking into the telephone. “Is that clear?” he concluded. “All right. Goodbye.” He hung up the receiver. “Come on, Bell. It’s Gravesend now. This is our busy day.” “Gravesend?” The superintendent stared. But it was into a teashop that Reggie plunged when they reached the street. He came out with large paper bags just as a big car turned painfully into Mawdleyn Lane. “Good man,” he smiled upon the chauffeur. “Gravesend police station. And let her out when you can.” With his mouth full he expounded to Superintendent Bell his theory of the evasion of Mr. Kuyper. As the car drew up in Gravesend a man in plain clothes came out of the police station. “Scotland Yard, sir?” Bell pulled a card out. “Inspector’s down on the beach now. I was to take you to him.” By the pier the inspector was waiting. He hurried up to their car. “Got him?” said Bell. “He’s off. You didn’t give us much time. But he’s been here. A man answering to your description hired a motor yacht--cutter with auxiliary engine--six weeks ago. It was rather noticed, being an unusual time of year to start yachting. He’s been down odd times and slept aboard. He seems to have slept aboard last night. I can’t find anyone who’s seen him here to-day. But there’s a longshoreman swears he saw a Tilbury boat go alongside the _Cyrilla_--that’s his yacht--a while since, and the _Cyrilla’s_ away.” “Have you got a fast boat ready for us?” “At the pier head, sir. Motor launch.” “Good work,” Reggie smiled. And they hurried on board. “What’s the job, sir?” The captain of the launch touched his cap. “Dig out after the _Cyrilla_. You know her, don’t you?”
