I know. I gather that the local superintendent has set a guard over the house and its inmates, so that no one who was known to have slept in the house last night has been allowed to leave.â
Sir Arthur nodded. âThat was done at once. But I cannot believe ââ
Stoddart held up his hand. âBelief does not enter into these cases, Sir Arthur. Now, I must ask you to give me particulars of as many of these said inmates as you can. First, your immediate circle.â
Sir Arthur drew his brows together. It was obvious that the task was not to his taste.
âOur immediate circle,â he repeated. âWell, first, there is, of course, the young couple for whom last nightâs ball was given â my younger brother and his American bride.â
âAmerican?â The inspector, who had taken out his notebook, held his pencil poised for a moment. âThe States, I suppose?â
âCalifornia,â Sir Arthur assented. âBut I do not imagine my young sister-in-law has spent much time in her native country. She was educated at a convent near Paris; when she left there she went for a long Continental tour with her father, Silas Juggs â the canned soup magnate, you know. Then she probably went home for a time, I am not sure. Later, she had one season in London when my brother fell a victim to her charms; result a violent love-affair, a short engagement, and a speedy marriage. No, as I see my sister-in-lawâs life there is no point in which it could have touched that of Charmian Karslake. Besides, she would have told us if she had known anything of Miss Karslake.â
âAh, of course,â the inspector murmured, as he made an entry in his notebook. âNow, Sir Arthur, the other members of the house-party â I have heard a Mr. Larpentâs name.â
âYes, Mr. John Larpent, a distant connexion, and my friend from boyhood,â Sir Arthur assented. âWe were at Eton and at Christ Church together. But of course you have heard of him before, inspector. He is doing extraordinarily well at the Bar.â
The inspector brought his hands together sharply. âOf course; I knew the name was familiar. It was he who defended Mrs. Gatwick last year.â
Sir Arthur nodded. âHe did not get her off, but it was a narrow shave. Quite possibly he may be able to help you, inspector. I fancy he has been making a few inquiries on his own.â
The inspector did not look particularly gratified. âWell, we shall see. Mr. Larpent is unmarried, I believe?â
âAt present.â Sir Arthur smiled faintly. âHe has lately become engaged to a friend of Lady Moretonâs â Miss Galbraith.â
The inspector looked up. âDaughter of Lord Galbraith?â
âThe last â not the present peer,â Sir Arthur corrected.
âShe would be here,â Stoddart said, as if stating a fact.
âShe was, naturally,â Sir Arthur assented.
The inspector glanced over his notes. âAnybody else? I mean guests. I shall have to get the servantsâ names from the housekeeper, I presume?â
âI expect so,â Sir Arthur said slowly. âAs for the other guests, there were in the bachelorsâ wing Captain Arthur Appley, Lord John Barton, Mr. Williams. But I made a list â here it is,â drawing a piece of paper from his pocket. âI thought it might save time. There, do you see, all the bachelors on this side. The unmarried ladies in the opposite wing.â
The inspector took the list and studied it in silence for a minute. Then he said without looking up:
âMiss Karslake did not sleep on this side of the house with the other unmarried ladies, I gather?â
âNo ââ Sir Arthur hesitated. âAs a matter of fact,â he went on, âLady Moreton was rather pleased â flattered perhaps I should say â at getting Miss Karslake to attend the ball, as she is reported to have
