was dead, and here was this woman, usually so calm and collected, unable to refrain from showing signs of violent grief at the news. Could it be possible--and Thornton Carey's cheeks tingled at the mere thought--that this woman had been some former mistress of Warren's, and that he had taken advantage of his intimacy with Griswold to obtain for her a comfortable place in his friend's household? No. Thornton Carey knew little of Warren, but all that he heard of him went to contradict such an idea; a man so generally represented as cold, impassive, and even more immersed in the accumulated cares of business than Griswold himself; there must be some other explanation of the mystery, but what it was Thornton Carey could not at the moment attempt to define. He began to find himself wishing that he had brought Bryan Duval with him to the house; for that gentleman's ready acuteness had made a great impression on Thornton Carey's mind, and he felt half inclined to start off at once and lay before his friend this newest phase in the mystery which they were endeavouring jointly to penetrate. It was absolutely necessary that some explanation should be given, and he thought he would say as much to Helen, whom he saw crossing the room to speak to him. 'She's a little better now,' murmured Helen, as she approached; 'she has regained her consciousness, but her heart is still beating wildly, and she has once or twice made an effort to speak, though her physical strength seems scarcely sufficient to admit of her doing so. What an extremely sudden seizure, was it not?' 'So sudden and so extraordinary, my dear Helen,' said Thornton Carey impressively, 'that I am eagerly desirous of having it accounted for; and even at the risk of somewhat tasking this woman's strength, I shall ask her to explain it as soon as possible.' 'You imagine, then, as I do,' said Helen, 'that it was her hearing the news of the accident which has happened to Mr. Warren that caused her to faint?' 'That and nothing else,' said Carey bluntly. 'Had you any idea that she was acquainted with Warren? Has she ever mentioned his name, or referred to him in any way? More than that, can you recollect whether she has ever shown any emotion when his name has been alluded to in her presence?' 'I had no idea that she was even aware of his existence,' said Helen. 'She came to me since poor Alston's departure, and in this house, at least, I am certain she has never set eyes upon Mr. Warren.' 'It is essential for the purposes of our investigation that we should know exactly what her relations with Warren are or were; and under your approval I purpose asking her a few questions.' 'You will not be hard upon her, Thornton?' said Helen, looking up at him. 'You will remember that the woman is poor and ill, and has already suffered a good deal from the loss of her own child--you will think of these things when you speak to her, I am sure?'
