"And you did not come out of it again until you joined the rest of the party downstairs?"
"No," she replied briefly.
He let her go, and sent for Edgar Mottisfont. If she had been belligerent, and Roydon patronising, Mottisfont provided a contrast to them both by using an ingratiating manner. That he was nervous was plain to be seen, but they were all nervous, the Inspector thought, and no wonder. Mottisfont seemed more shocked than any of them, reiterating his horror, and his incomprehension. He had been intimately acquainted with Nathaniel for close on thirty years; for many years he had spent Christmas with Nathaniel. Nothing like this, he said, unconscious of absurdity, had ever happened before.
"I understand there had been some unpleasantness," the Inspector said.
"He was a hard man. Out of touch with the younger generation, you know. It was Miss Herriard's fault for bringing Roydon here. She should have known better! However, that's not my affair. I've never pretended to understand that couple. Seemed to take a delight in annoying their uncle! I don't know why Herriard put up with them, but there's no doubt he was fond of them, in his way."
"May I ask, sir, if Miss Herriard had any particular reason for bringing Mr. Roydon here?"
Mottisfont seemed to feel that he had said too much. He replied evasively: "You'd better ask her. It had nothing to do with me."
"There was no quarrel between yourself and Mr. Herriard?"
As he put the question, the Inspector knew that there had been a quarrel. It was as though a curtain was drawn swiftly over Mottisfont's face, shutting him in. He had been a little off his guard, talking querulously about the young Herriards, but now he was wary again, trying to make up his mind, the Inspector guessed, what he should say. Probably he didn't know who might have overheard his quarrel; didn't dare lie; didn't want to tell the truth. All the same, these nervous witnesses! The Inspector waited, keeping his gaze steady on Mottisfont's face.
The weak grey eyes behind Mottisfont's spectacles shifted. "Not a quarrel. Oh, dear me, no! Nothing of that sort! Why, we've been in partnership for twenty-five years! What an idea! We merely disagreed about a matter purely concerned with the business. Herriard was more or less of a sleeping-partner, you know, but very fond of interfering with the actual running of the business, if you gave him the chance. A little old-fashioned: didn't move with the times. Many's the battle-royal we've waged! But I think I may claim to have been able to handle him!"
