She immediately produced, not only a photograph of her husband, but also one of the girl Trennatt, which she said belonged to the cook. Hewitt complimented her on her foresight. “And now,” he said, “I think we’ll go and take a look at Mr. Geldard’s office, if we may. Of course I shall follow him up now.” Hewitt made a sign to me, which I interpreted as asking whether I would care to accompany him. I assented with a nod, for the case seemed likely to be interesting.

I omit most of Mrs. Geldard’s talk by the way, which was almost ceaseless, mostly compounded of useless repetition, and very tiresome.

The office was on a third floor in a large building in Finsbury Pavement. The caretaker made no difficulty in admitting us. There were two rooms, neither very large, and one of them at the back very small indeed. In this was a small locked door.

“That leads on to the small staircase, sir,” the caretaker said in response to Hewitt’s inquiry. “The staircase leads down to the basement, and it ain’t used much ’cept by the cleaners.”

“If I went down this back staircase,” Hewitt pursued, “I suppose I should have no difficulty in gaining the street?”

“Not a bit, sir. You’d have to go a little way round to get into Finsbury Pavement, but there’s a passage leads straight from the bottom of the stairs out to Moorfields behind.”

“Yes,” remarked Mrs. Geldard bitterly, when the caretaker had left the room, “that’s the way he’s been leaving the office every day, and in disguise, too.” She pointed to the cupboard where her husband’s clothes lay. “Pretty plain proof that he was ashamed of his doings, whatever they were.”

“Come, come,” Hewitt answered deprecatingly, “we’ll hope there’s nothing to be ashamed of—at any rate till there’s proof of it. There’s no proof as yet that your husband has been disguising. A great many men who rent offices, I believe, keep dress clothes at them—I do it myself—for convenience in case of an unexpected invitation, or such other eventuality. We may find that he returned here last night, put on his evening dress, and went somewhere dining. Illness, or fifty accidents, may have kept him from home.”

But Mrs. Geldard was not to be softened by any such suggestion, which I could see Hewitt had chiefly thrown out by way of pacifying the lady, and allaying her bitterness as far as he could, in view of a possible reconciliation when things were cleared up.

“That isn’t very likely,” she said. “If he kept a dress suit here openly, I should know of it; and if he kept it here unknown to me, what did he want it for? If he went out in dress clothes last night, who did he go with? Who do you suppose, after seeing those envelopes and that piece of the letter?”
