the information would be more or less valueless until the afternoon, and he forthwith proceeded upon the investigation which he had planned out.

The road was still muddy, and the track of the tyres, which were of somewhat peculiar pattern, clearly visible. He followed it along the road for a matter of a mile and a half. Then he came to a standstill before a plain oak gate and was conscious of a distinct shock. On the top bar of the gate was painted in white letters.

and it needed only the most cursory examination to establish the fact that the car whose track he had been following had turned in here. He held up his hand and stopped a luggage trolley which had just turned the bend in the avenue. The man pulled up and touched his hat.

"Where are you off to, Fellowes?" Julian enquired.

"I am going to Holt station, sir," the man replied, "after some luggage."

"Are there any guests at the Hall who motored here, do you know?" Julian asked.

"Only the young lady, sir," the man replied, "Miss Abbeway. She came in a little coupe Panhard."

Julian frowned thoughtfully.

"Has she been out in it this morning?" he asked.

The man shook his head.

"She broke down in it yesterday afternoon, sir," he answered, "about halfway up to the Hall here."

"Broke down?" Julian repeated. "Anything serious? Couldn't you put it right for her?"

"She wouldn't let me touch it, sir," the man explained. "She said she had two cracked sparking plugs, and she wanted to replace them herself. She has had some lessons, and I think she wanted a bit of practice."

"I see. Then the car is in the avenue now?"

"About half a mile up, on the left-hand side, sir, just by the big elm. Miss Abbeway said she was coming down this afternoon to put new plugs in."

"Then it's been there all the time since yesterday afternoon?" Julian persisted.

"The young lady wished it left there, sir. I could have put a couple of plugs in, in five minutes, and brought her up to the house, but she wouldn't hear of it."

"I see, Fellowes."

"Any luck with the geese last night, sir?" the man asked. "I heard there was a pack of them on Stiffkey Marshes."

"I got one. They came badly for us," Julian replied.

He made his way up the avenue. At exactly the spot indicated by the chauffeur a little coupe car was standing, drawn on to the turf. He glanced at the name of the maker and looked once more at the tracks upon the drive. Finally, he decided that his investigations were leading him in a most undesirable direction.

He turned back, walked across the marshes, where he found nothing to disturb him, and lunched with Furley, whose leg was now so much better that he was able to put it to the ground.

"What about this visitor of yours?" Julian asked, as they sat smoking afterwards. "I must be back at the Hall in time to dine to-night, you know. My people made rather a point of it."

Furley nodded.

"You'll be all right," he replied. "As a matter of fact, he isn't coming."

"Not coming?" Julian repeated. "Jove, I should have thought you'd have had intelligence officers by the dozen down here!"

"For some reason or other," Furley confided, "the affair has been handed over to the military authorities. I have had a man down to see me this morning, and he has taken full particulars. I don't know that they'll even worry you at all—until later on, at any rate."

"Jove, that seems queer!"

"Last night's happening was queer, for that matter," Furley continued. "Their only chance, I suppose, of getting to the bottom of it is to lie doggo as far as possible. It isn't like a police affair, you see. They don't want witnesses and a court of justice. One man's word and a rifle barrel does the trick."

Julian sighed.

"I suppose," he observed, "that if I do my duty as a loyal subject, I shall drop the curtain on last night. Seems a pity to have had an adventure like that and not be able to open one's mouth about it."

Furley grunted.

"You don't want to join the noble army of gas bags," he said. "Much better make up your mind that it was a dream."

"There are times," Julian confided, "when I am not quite sure that it wasn't."
