“On that evening the horses had been exercised and watered as usual, and the stables were locked up at nine o’clock. Two of the lads walked up to the trainer’s house, where they had supper in the kitchen, while the third, Ned Hunter, remained on guard. At a few minutes after nine the maid, Edith Baxter, carried down to the stables his supper, which consisted of a dish of curried mutton. She took no liquid, as there was a water-tap in the stables, and it was the rule that the lad on duty should drink nothing else. The maid carried a lantern with her, as it was very dark and the path ran across the open moor.

“Edith Baxter was within thirty yards of the stables when a man appeared out of the darkness and called to her to stop. As she stepped into the circle of yellow light thrown by the lantern she saw that he was a person of gentlemanly bearing, dressed in a gray suit of tweeds, with a cloth cap. He wore gaiters and carried a heavy stick with a knob to it. She was most impressed, however, by the extreme pallor of his face and by the nervousness of his manner. His age, she thought, would be rather over thirty than under it.

“ ‘Can you tell me where I am?’ he asked. ‘I had almost made up my mind to sleep on the moor when I saw the light of your lantern.’

“ ‘You are close to the King’s Pyland training stables,’ said she.

“ ‘Oh, indeed! What a stroke of luck!’ he cried. ‘I understand that a stable-boy sleeps there alone every night. Perhaps that is his supper which you are carrying to him. Now I am sure that you would not be too proud to earn the price of a new dress, would you?’ He took a piece of white paper folded up out of his waistcoat pocket. ‘See that the boy has this to-night, and you shall have the prettiest frock that money can buy.’

“She was frightened by the earnestness of his manner and ran past him to the window through which she was accustomed to hand the meals. It was already opened, and Hunter was seated at the small table inside. She had begun to tell him of what had happened when the stranger came up again.

“ ‘Good-evening,’ said he, looking through the window. ‘I wanted to have a word with you.’ The girl has sworn that as he spoke she noticed the corner of the little paper packet protruding from his closed hand.

“ ‘What business have you here?’ asked the lad.

“ ‘It’s business that may put something into your pocket,’ said the other. ‘You’ve two horses in for the Wessex Cup-Silver Blaze and Bayard. Let me have the straight tip and you won’t be a loser. Is it a fact that at the weights Bayard could give the other a hundred yards in five furlongs, and that the stable have put their money on him?’

“ ‘So, you’re one of those damned touts!’ cried the lad. ‘I’ll show you how we serve them in King’s Pyland.’ He sprang up and rushed across the stable to unloose the dog. The girl fled away to the house, but as she ran she looked back and saw that the stranger was leaning through the window. A minute later, however, when Hunter rushed out with the hound he was gone, and though he ran all round the buildings he failed to find any trace of him.”

“One moment,” I asked. “Did the stable-boy, when he ran out with the dog, leave the door unlocked behind him?”

“Excellent, Watson, excellent!” murmured my companion. “The importance of the point struck me so forcibly that I sent a special wire to Dartmoor yesterday to clear the matter up. The boy locked the door before he left it. The window, I may add, was not large enough for a man to get through.
