Granet, a few days later, brought his car to a standstill in front of an ordinary five-barred gate upon which was painted in white letters "Market Burnham Hall." A slight grey mist was falling and the country inland was almost blotted from sight. On the other side of the gate a sandy driver disappeared into an avenue of ragged and stunted elm trees, which effectually concealed any view of the house.
"Seems as though the girl were right," Granet muttered to himself. "However, here goes."He backed his car close to the side of the hedge, and laying his hand upon the latch of the gate, prepared to swing it open. Almost immediately a figure stepped out from the shrubs.
"Halt!"
Granet looked with surprise at the khaki-clad figure.
"Your name and destination?" the man demanded.
"Captain Granet of the Royal Fusiliers, home from the Front on leave," Granet replied. "I was going up to the Hall to call on Miss Worth.""Stay where you are, if you please, sir," the man replied.
He stepped back into the sentry box and spoke through a telephone. In a moment or two he reappeared.
"Pass on, please, sir," he said.
Granet walked slowly up the avenue, his hands behind him, a frown upon his forehead. Perhaps, after all, things were not to be so easy for him. On either side he could see the stretches of sand, and here and there the long creeks of salt water. As he came nearer to the house, the smell of the sea grew stronger, the tops of the trees were more bowed than ever, sand was blown everywhere across the hopeless flower-beds. The house itself, suddenly revealed, was a grim weather-beaten structure, built on the very edge of a queer, barrow-like tongue of land which ended with the house itself. The sea was breaking on the few yards of beach sheer below the windows. To his right was a walled garden, some lawns and greenhouses; to the left, stables, a garage, and two or three labourer's cottages. At the front door another soldier was stationed doing sentry duty. He stood on one side, however, and allowed Granet to ring the bell.
"Officers quartered here?" Granet inquired.
"Only one, sir," the man replied.
The door was opened almost immediately by a woman-servant. She did not wait for Granet to announce himself but motioned him to follow her into a large, circular, stone hall, across which she led him quickly and threw open the door of the drawing-room. Isabel Worth was standing just inside the room, as though listening. She held out her hand and there was no doubt about her welcome.
"Captain Granet," she said almost in a whisper, "of course you'll think we are all mad, but would you mind coming upstairs into my little sitting-room?""Of course not," Granet acquiesced. "I'll come anywhere, with pleasure. What a view you have from here!"He glanced through the high windows at the other end of the room. She laid her fingers upon his arm and led him towards the door.
"Quietly, please," she whispered. "Try and imagine that you are in a house of conspirators."She led him up the quaint stone staircase, spiral-shaped, to the first floor.
Arrived there, she paused to listen for a moment, then breathed a little more freely and led him to a small sitting-room at the end of a long passage. It was a pleasant little apartment and looked sheer out over the sea. She threw herself down upon a sofa with a sigh of relief, and pointed to a chair.
"Do sit down, Captain Granet," she begged. "I am really not in the least insane but father is. You know, I got back on Wednesday night and was met at once with stern orders that no visitors of any sort were to be received, that the tradespeople were to be interviewed at the front gates--in fact that the house was to be in a state of siege."Granet appeared puzzled.
"But why?"
"Simply because dad has gone out of his senses," she replied wearily. "Look here."She led him cautiously to the window and pointed downwards. About fifty yards out at sea was a queer wooden structure, set up on strong supports. From where they were, nothing was to be seen but a windowless wall of framework and a rope ladder. Underneath, a boat was tethered to one of the supports. About thirty yards away, a man was rowing leisurely around in another small boat.
