"My God!" cried she, and sat staring at him; then rose up and began to move towards the door backwards, keeping an eye upon him. Her thought showed clear to the detective: she had been entertaining a lunatic. He laughed.
"Don't go," he said. "I know what you imagine, but I'm no lunatic. I don't believe that your son is an impostor. He is a friend of mine, and I know that he is Arthur Dillon. But a man in my business must do as he is ordered by his employers. I am a detective."
For a minute she hesitated with hand outstretched to the bell-rope. Her mind acted with speed; she had nothing to fear, the man was friendly, his purpose had failed, whatever it was, the more he talked the more she would learn, and it might be in her power to avert danger by policy. She went back to her seat, having left it only to act her part. Taking the hint provided by Curran, she pretended belief in his insanity, and passed to indignation at this attempt upon her happiness, her motherhood. This rage became real, when she reflected that the Aladdin palace of her life was really threatened by Curran's employers. To her the prosperity and luxury of the past five years had always been dream-like in its fabric, woven of the mists of morning, a fairy enchantment, which might vanish in an hour and leave poor Cinderella sitting on a pumpkin by the roadside, the sport of enemies, the burden of friends. How near she had been to this public humiliation! What wretches, these people who employed the detective!
"My dear boy was absent ten years," she said, "and I suffered agony all that time. What hearts must some people have to wish to put me through another time like that! Couldn't any wan see that I accepted him as my son? that all the neighbors accepted him? What could a man want to deceive a poor mother so? I had nothing to give him but the love of a mother, and men care little for that, wild boys care nothing for it. He brought me a fortune, and has made my life beautiful ever since he came back. I had nothing to give him. Who is at the bottom of this thing?"
The detective explained the existence and motives of a deserted, poverty-stricken wife and child.
"I knew a woman would be at the bottom of it," she exclaimed viciously, feeling against Sonia a hatred which she knew to be unjust. "Well, isn't she able to recognize her own husband? If I could tell my son after ten years, when he had grown to be a man, can't she tell her own husband after a few years? Could it be that my boy played Horace Endicott in Boston and married that woman, and then came back to me?"
"Oh, my dear Mrs. Dillon," cried the detective in alarm, "do not excite yourself over so trifling a thing. Your son is your son no matter what our theories may be. This Endicott was born and brought up in the vicinity of Boston, and came from a very old family. Your suspicion is baseless. Forget the whole matter I beg of you."
"Have you a picture of the young man?"
He handed her the inevitable photograph reluctantly, quite sure that she would have hysterics before he left, so sincere was her excitement. Anne studied the portrait with keen interest, it may be imagined, astonished to find it so different from Arthur Dillon. Had she blundered as well as the detective? Between this portrait and any of the recent photographs of Arthur there seemed no apparent resemblance in any feature. She had been exciting herself for nothing.
"Wonderful are the ways of men," was her comment. "How any one ..." her brogue had left her ... "could take Arthur Dillon for this man, even supposing he was disguised now, is strange and shameful. What is to be the end of it?"
