Poirot seemed somewhat crest-fallen. Meanwhile the magistrate had summoned Marchaud. “My compliments to Madame Renauld, and I should be glad to speak to her for a few minutes. Beg her not to disturb herself. I will wait upon her upstairs.” Marchaud saluted and disappeared. We waited some minutes, and then, to our surprise, the door opened, and Mrs. Renauld, deathly pale in her heavy mourning, entered the room. M. Hautet brought forward a chair, uttering vigorous protestations, and she thanked him with a smile. Stonor was holding one hand of hers in his with an eloquent sympathy. Words evidently failed him. Mrs. Renauld turned to M. Hautet. “You wished to ask me something, M. le juge.” “With your permission, madame. I understand your husband was a French Canadian by birth. Can you tell me anything of his youth, or upbringing?” She shook her head. “My husband was always very reticent about himself, monsieur. He came from the North West, I know, but I fancy that he had an unhappy childhood, for he never cared to speak of that time. Our life was lived entirely in the present and the future.” “Was there any mystery in his past life?” Mrs. Renauld smiled a little, and shook her head. “Nothing so romantic, I am sure, M. le juge.” M.

Bex leaned forward and said gently: “We regret to cause you pain, madame, but have you any reason to believe that Madame Daubreuil was your husband’s mistress?” With a sob of anguish, Mrs. Renauld buried her face in her hands. Her shoulders heaved convulsively. At last she lifted her head, and said brokenly: “She may have been.” Never, in all my life, have I seen anything to equal the blank amazement on Stonor’s face. He was thoroughly taken aback. 11 Jack Renauld What the next development of the conversation would have been, I cannot say, for at that moment the door was thrown violently open, and a tall young man strode into the room. Just for a moment I had the uncanny sensation that the dead man had come to life again. Then I realized that this dark head was untouched with grey, and that, in point of fact, it was a mere boy who now burst in among us with so little ceremony. He went straight to Mrs. Renauld with an impetuosity that took no heed of the presence of others. “Mother!”
