SURPRISE silenced Hugh for the moment. Iris understood the look that he fixed on her, and answered it. “I am quite sure,” she told him, “of what I say.”

Mountjoy’s well-balanced mind hesitated at rushing to a conclusion.

“I am sure you are convinced of what you tell me,” he said. “But mistakes do sometimes happen in forming a judgment of handwriting.”

In the state of excitement that now possessed her, Iris was easily irritated; she was angry with Hugh for only supposing that she might have made a mistake. He had himself, as she reminded him, seen Lord Harry’s handwriting in past days. Was it possible to be mistaken in those bold thickly-written characters, with some of the letters so quaintly formed? “Oh, Hugh, I am miserable enough as it is,” she broke out; “don’t distract me by disputing what I know! Think of a woman so kind, so disinterested, so charming — the very opposite of a false creature — think of Mrs. Vimpany having deceived me!”

There was not the slightest reason, thus far, for placing that interpretation on what had happened. Mountjoy gently, very gently, remonstrated.

“My dear, we really don’t know yet that Mrs. Vimpany has been acting under Lord Harry’s instructions. Wait a little before you suspect your fellow-traveller of offering her services for the purpose of deceiving you.”

Iris was angry with him again: “Why did Mrs. Vimpany never tell me she knew Lord Harry? Isn’t that suspicious?”

Mountjoy smiled. “Let me put a question on my side,” he said. “Did you tell Mrs. Vimpany you knew Lord Harry?” Iris made no reply; her face spoke for her. “Well, then,” he urged, “is your silence suspicious? I am far, mind, from saying that this may not be a very unpleasant discovery. Only let us be sure first that we are right.”

With most of a woman’s merits, Miss Henley had many of a woman’s faults. Still holding to her own conclusion, she asked how they could expect to be sure of anything if they addressed their inquiries to a person who had already deceived them.

Mountjoy’s inexhaustible indulgence still made allowances for her. “When Mrs. Vimpany comes back,” he said, “I will find an opportunity of mentioning Lord Harry’s name. If she tells us that she knows him, there will be good reason in that one circumstance, as it seems to me, for continuing to trust her.”

“Suppose she shams ignorance,” Iris persisted, “and looks as if she had never heard of his name before?”

“In that case, I shall own that I was wrong, and shall ask you to forgive me.”

The finer and better nature of Iris recovered its influence at these words. “It is I who ought to beg pardon,” she said. “Oh, I wish I could think before I speak: how insolent and ill-tempered I have been! But suppose I turn out to be right, Hugh, what will you do then?”

“Then, my dear, it will be my duty to take you and your maid away from this house, and to tell your father what serious reasons there are”—— He abruptly checked himself. Mrs. Vimpany had returned; she was in perfect possession of her lofty courtesy, sweetened by the modest dignity of her smile.

“I have left you, Miss Henley, in such good company,” she said, with a gracious inclination of her head in the direction of Mountjoy, “that I need hardly repeat my apologies — unless, indeed, I am interrupting a confidential conversation.”

It was possible that Iris might have betrayed herself, when the doctor’s wife had looked at her after examining the address on the packet. In this case Mrs. Vimpany’s allusion to “a confidential conversation” would have operated as a warning to a person of experience in the by-ways of deceit. Mountjoy’s utmost exertion of cunning was not capable of protecting him on such conditions as these. The opportunity of trying his proposed experiment with Lord Harry’s name seemed to have presented itself already. He rashly seized on it.

“You have interrupted nothing that was confidential,” he hastened to assure Mrs. Vimpany. “We have been speaking of a reckless young gentleman, who is an acquaintance of ours. If what I hear is true, he has already become public property; his adventures have found their way into some of the newspapers.”

Here, if Mrs. Vimpany had answered Hugh’s expectations, she ought to have asked who the young gentleman was. She merely listened in polite silence.

With a woman’s quickness of perception, Iris saw that Mountjoy had not only pounced on his opportunity prematurely, but had spoken with a downright directness of allusion which must at once have put such a ready-witted person as Mrs. Vimpany on her guard. In trying to prevent him from pursuing his unfortunate experiment in social diplomacy, Iris innocently repeated Mountjoy’s own mistake. She, too, seized her opportunity prematurely. That is to say, she was rash enough to change the subject.

“You were talking just now, Hugh, of our friend’s adventures,” she said; “I am afraid you will find yourself involved in an adventure of no very agreeable kind, if you engage a bed at the inn. I never saw a more wretched-looking place.”

It was one of Mrs. Vimpany’s many merits that she seldom neglected an opportunity of setting her friends at their ease.

“No, no, dear Miss Henley,” she hastened to say; “the inn is really a more clean and comfortable place than you suppose. A hard bed and a scarcity of furniture are the worst evils which your friend has to fear. Do you know,” she continued, addressing herself to Mountjoy, “that I was reminded of a friend of mine, when you spoke just now of the young gentleman whose adventures are in the newspapers. Is it possible that you referred to the brother of the present Earl of Norland? A handsome young Irishman — with whom I first became acquainted many years since. Am I right in supposing that you and Miss Henley know Lord Harry?” she asked.

What more than this could an unprejudiced mind require? Mrs. Vimpany had set herself right with a simplicity that defied suspicion. Iris looked at Mountjoy. He appeared to know when he was beaten. Having acknowledged that Lord Harry was the young gentleman of whom he and Miss Henley had been speaking, he rose to take leave.

After what had passed, Iris felt the necessity of speaking privately to Hugh. The necessary excuse presented itself in the remote situation of the inn. “You will never find your way back,” she said, “through the labyri............
