Constable Walker walked rapidly back, and as he did so the same clock struck ten. He had been gone exactly an hour. In the meantime, Inspector Burnley got a taxi and, after a careful examination of his route and the district on a large scale map, started for St. Malo with three other men. He called on his way at Walpole Terrace, Queen Mary Road, where Tom Broughton lived and delighted that young man by inviting him to join the party. On the way, he explained in detail the lie of the house and grounds, where he wanted each man to stand, and what was to be done in various eventualities. The streets were full of people and motoring was slow, but it was still considerably before eleven when they entered the Great North Road. They ran on till the Inspector judged they were not far from the house, when the car was run up a side road and the engine stopped. The five men then walked on in silence. ‘Wait here,’ whispered Burnley, when they had gone some distance, and slipped away into the dark. He found the lane, walked softly down it until he came to the little gate, slipped inside and came up to Constable Walker standing behind his tree. ‘I’m Inspector Burnley,’ he whispered. ‘Has any one come in or out yet?’ ‘No, sir.’ ‘Well, wait here until I post my men.’ He returned to the others and, speaking in a whisper, gave his directions. ‘You men take up the positions I explained to you. Listen out for a whistle to close in. Mr. Broughton, you come with me and keep silent.’ The Inspector and his young acquaintance walked down the lane, stopping outside the little gate. The other three men posted themselves at various points in the grounds. And then they waited. It seemed to Broughton that several hours must have passed when a clock in the distance struck twelve. He and the Inspector were standing beside each other concealed under the hedge. Once or twice he had attempted whispered remarks, but Burnley was not responsive. It was rather cold and the stars were bright. A light breeze had risen and it rustled gently through the hedge and stirred the branches of the trees. An insistent dog was barking somewhere away to the right. A cart passed on the road, the wheels knocking on their axles annoyingly. It took ages to get out of earshot, the sounds coming in rotation through nearly a quarter of the compass. Then a car followed with a swift rush, the glare of the headlights glancing along through the trees. And still nothing happened. After further ages the clock struck again--one. A second dog began barking. The breeze freshened, and Broughton wished he had brought a heavier coat. He longed to stamp up and down and ease his cramped limbs. And then the latch of the road gate clicked and footsteps sounded on the gravel.
