her mind, for when Charles and Peter came back from seeing the Colonel out, she suddenly said: "Though mind you, Peter, if there were a ghost here I know just what I should do."
"Of course you do, darling," said Charles. "You'd put your head under the clothes, and say your prayers, same as you did when your flat was burgled."
Mrs. Bosanquet was quite unabashed. "I should instantly summon the Vicar to exorcise it," she said with dignity.
Charles' shout of laughter was broken off sharply. A sound, like a groan, muffled as though by stone walls, startled him into silence. "Good God, what's that?" he rapped out.
Celia had grown suddenly white, and instinctively Margaret drew closer to her brother. The groan had held a note almost like a wail, long-drawn-out and slowly dying.
No one answered Charles for a moment. Only Celia gave a little shiver, and glanced round fearfully. Mrs. Bosanquet broke the awed silence. "What is what, my dear?" she asked calmly.
"Didn't you hear it?" Margaret said. "As though - as though - someone - gave an awful — groan."
"No, my dear, but you know I don't hear very well. Probably a creaking door."
Charles recovered himself. "Not only probably, but undoubtedly," he said. "It startled me for the moment. Comes of talking about ghosts. I'm going round with an oil-can." He left the room, ignoring an involuntary cry from his wife.
"Do you really think it was that?" Margaret said. "I'm not being spooky, but - but it seemed to come from underneath somewhere."
"Don't be an ass, Peg," her brother advised her. "If you ask me it came from outside. I'll bet it's the door leading out of the garden-hall. I meant to oil the hinge before, and it's got worse after the rain we had last night."
"If you're going to look, I'm coming with you," Margaret said firmly.
Celia half-rose from her chair, and then sat down again.
"I shall stay and keep Aunt Lilian company," she announced in the voice of a heroine. "Whoever heard of a daylight ghost? We're all getting nervy. I shall bar ghost-talk for the future."
In the garden-hall, where Celia was in the habit of filling the flower-vases, Peter and Margaret found Charles with Bowers beside him, holding an oil-can in a shaking hand.
"Oh, so you thought it was this door too, did you?" Peter said. "What's the matter with you, Bowers?"
Bowers cast him a look of reproach. "We heard it, sir, Mrs. Bowers and me. Seemed to come from somewhere quite close. It gave Mrs. Bowers such a turn she nearly dropped her frying-pan. "Good gracious alive!" she said. "Who's being murdered?" And she's not one to fancy things, sir, as you well know." Gloomily he watched Charles open the door into the garden. It squeaked dismally, but the sound was not the groan they had heard before. "No, sir, it's not that, and nor it's not any other door in the house, though they do squeak, I won't deny. There's something uncanny about this place. I said it as soon as I set eyes on it, and I can tell you, sir, it's taking years off my life, living here."
"Is there any other door leading out on this side of the house?" Peter said. "I could swear it came from this direction."
"There'ss only the long window in the drawing-room," said Margaret. She stepped out on to the gravel-path, and looked along the side of the house. "I can't see any other. I say, it is rather beastly, isn't it? Of course I know things do echo in these places, but… Why, who's that?"
Charles came quickly out to her side. "Where?" he said sharply. "Hullo, there's a chap walking past the shrubbery!" He started forward, Peter at his heels, and hailed the stranger rather sharply.
A man in fisherman's attire, and carrying a creel and a rod, was walking through the trees beyond the shrubs that ran close up to the wall of the house. He stopped as Charles hailed him, and came to meet him. He was a dark young man of about thirty, with very black brows that grew close over the bridge of his nose, and a mouth that was rather grim in repose.
