It was now shortly after eight, and the car had arrived with the two men sent back the previous evening. Burnley gave them instructions about keeping a watch on Felix, then with Sergeant Hastings and Constable Walker he entered the car and was driven rapidly towards London. CHAPTER VII THE CASK AT LAST Inspector Burnley reached Scotland Yard, after dropping Constable Walker at his station with remarks which made the heart of that observer glow with triumph and conjured up pictures of the day when he, Inspector Walker, would be one of the Yard’s most skilled and trusted officers. During the run citywards Burnley had thought out his plan of campaign, and he began operations by taking Sergeant Hastings to his office and getting down the large scale map. ‘Look here, Hastings,’ he said, when he had explained his theories and found what he wanted. ‘Here’s John Lyons and Son, the carriers where Watty is employed, and from where the dray was hired. You see it’s quite a small place. Here close by is Goole Street, and here is the Goole Street Post Office. Got the lay of those? Very well. I want you, when you’ve had your breakfast, to go out there and get on the track of Watty. Find out first his full name and address, and wire or phone it at once. Then shadow him. I expect he has the cask, either at his own house or hidden somewhere, and he’ll lead you to it if you’re there to follow. Probably he won’t be able to do anything till night, but of that we can’t be certain. Don’t interfere or let him see you if possible, but of course don’t let him open the cask if he has not already done so, and under no circumstances allow him to take anything out of it. I will follow you out and we can settle further details. The Goole Street Post Office will be our headquarters, and you can advise me there at, say, the even hours of your whereabouts. Make yourself up as you think best and get to work as quickly as you can.’ The sergeant saluted and withdrew. ‘That’s everything in the meantime, I think,’ said Burnley to himself, as with a yawn he went home to breakfast. When some time later Inspector Burnley emerged from his house, a change had come over his appearance. He seemed to have dropped his individuality as an alert and efficient representative of Scotland Yard and taken on that of a small shop-keeper or contractor in a small way of business. He was dressed in a rather shabby suit of checks, with baggy knees and draggled coat. His tie was woefully behind the fashion, his hat required brushing, and his boots were soiled and down at heel. A slight stoop and a slouching walk added to his almost slovenly appearance. He returned to the Yard and asked for messages. Already a telephone had come through from Sergeant Hastings: ‘Party’s name, Walter Palmer, 71 Fennell Street, Lower Beechwood Road.’ Having had a warrant made out for the ‘party’s’ arrest, he got a police motor with plain-clothes driver, and left for the scene of operations.
