Mrs. Seton had kept up remarkably well during Hewitt’s examination, but she was plainly by no means a strong woman, and her maid came again to her assistance as Hewitt left. Hewitt himself made for the police station. Few inspectors indeed of the Metropolitan Police force did not know Hewitt by sight, and the one here in charge knew him well. He remembered very well the occasion, six weeks or so before, when Mrs. Clark brought Mrs. Seton’s child to the station. He was on duty himself at the time, and he turned up the book containing an entry on the subject. From this it appeared that the lady gave the address No. 89, Sedgby Road, Belsize Park. “I suppose you didn’t happen to know the lady,” Hewitt asked--“by sight or otherwise?” “No, I didn’t, and I’m not sure I could swear to her again,” the inspector answered. “She wore a heavy veil, and I didn’t see much of her face. One rum thing I noticed, though: she seemed rather taken with the baby, and as she stooped down to kiss him before she went away I could see an old scar on her throat. It was just the sort of scar I’ve seen on a man that’s had his throat cut and got over it. She wore a high collar to hide it, but stooping shifted the collar, and so I saw it.” “Did she seem an educated woman?” “Oh yes; perfect lady; spoke very nice. I told her a baby had been inquired after by Mrs. Seton, and from the description I’d no doubt this was the one. And so it was.” “At what time was this?” “7.10 p.m., exactly. Here it is, all entered properly.” “Now as to Sedgby Road, Belsize Park. Do you happen to know it?” “Oh, yes, very well. Very quiet, respectable road indeed. I only know it through walking through.” “I see a suburban directory on the shelf behind you. Do you mind pulling it down? Thanks. Let us find Sedgby Road. Here it is. See, there _is_ no No. 89; the highest number is 67.” “No more there is,” the inspector answered, running his finger down the column; “and there’s no Clark in the road, that’s more. False address, that’s plain. And so they’ve lost him again, have they? We had notice yesterday, of course, and I’ve just got some bills. This last seems a queer sort of affair, don’t it? Child sitting inside the house disappeared like a ghost, and all the doors and windows fastened inside.”
