"If I don't put a stop to this, they'll spoil everything," he said to himself.

He stood in an angle of the house, invisible in the darkness, and measured the distance between himself and the gate. The gate was open. To his right, he saw the steps, on the top of which the people were flinging themselves about; to his left, the building occupied by the portress.

The woman had come out of her lodge and was standing near the people, entreating them:

"Oh, do be quiet, do be quiet! He'll come!"

"Capital!" said Lupin. "The good woman is an accomplice of these as well. By Jingo, what a pluralist!"

He rushed across to her and, taking her by the scruff of the neck, hissed:

"Go and tell them I've got the child... They can come and fetch it at my place, Rue Chateaubriand."

A little way off, in the avenue, stood a taxi which Lupin presumed to be engaged by the gang. Speaking authoritatively, as though he were one of the accomplices, he stepped into the cab and told the man to drive him home.

"Well," he said to the child, "that wasn't much of a shake-up, was it?... What do you say to going to bye-bye on the gentleman's bed?"

As his servant, Achille, was asleep, Lupin made the little chap comfortable and stroked his hair for him. him The child seemed numbed. His poor face was as though petrified into a stiff expression made up, at one and the same time, of fear and the wish not to show fear, of the longing to scream and a pitiful effort not to scream.

"Cry, my pet, cry," said Lupin. "It'll do you good to cry."

The child did not cry, but the voice was so gentle and so kind that he relaxed his tense muscles; and, now that his eyes were calmer and his mouth less contorted, Lupin, who was examining him closely, found something that he recognized, an undoubted resemblance.

This again confirmed certain facts which he suspected and which he had for some time been linking in his mind. Indeed, unless he was mistaken, the position was becoming very different and he would soon assume the direction of events. After that...

A ring at the bell followed, at once, by two others, sharp ones.

"Hullo!" said Lupin to the child. "Here's mummy come to fetch you. Don't move."

He ran and opened the door.

A woman entered, wildly:

"My son!" she screamed. "My son! Where is he?"

"In my room," said Lupin.

Without asking more, thus proving that she knew the way, she rushed to the bedroom.

"As I thought," muttered Lupin. "The youngish woman with the gray hair: Daubrecq's friend and enemy."

He walked to the window and looked through the curtains. Two men were striding up and down the opposite pavement: the Growler and the Masher.

"And they're not even hiding themselves," he said to himself. "That's a good sign. They consider that they can't do without me any longer and that they've got to obey the governor. There remains the pretty lady with the gray hair. That will be more difficult. It's you and I now, mummy."

He found the mother and the boy clasped in each other's arms; and the mother, in a great state of alarm, her eyes moist with tears, was saying:

“Mr. Gibson has his enemies, as anyone would expect who knew him and his methods,” said he. “He sleeps with a loaded revolver in the drawer beside his bed. He is a man of violence, sir, and there are times when all of us are afraid of him. I am sure that the poor lady who has passed was often terrified.”

“Did you ever witness physical violence towards her?”

“No, I cannot say that. But I have heard words which were nearly as bad — words of cold, cutting contempt, even before the servants.”

“Our millionaire does not seem to shine in private life,” remarked Holmes as we made our way to the station. “Well, Watson, we have come on a good many facts, some of them new ones, and yet I seem some way from my conclusion. In spite of the very evident dislike which Mr. Bates has to his employer, I gather from him that when the alarm came he was undoubtedly in his library. Dinner was over at 8:30 and all was normal up to then. It is true that the alarm was somewhat late in the evening, but the tragedy certainly occurred about the hour named in the note. There is no evidence at all that Mr. Gibson had been out of doors since his return from town at five o’clock. On the other hand, Miss Dunbar, as I understand it, admits that she had made an appointment to meet Mrs. Gibson at the bridge. Beyond this she would say nothing, as her lawyer had advised her to reserve her defence. We have several very vital questions to ask that young lady, and my mind will not be easy until we have seen her. I must confess that the case would seem to me to be very black against her if it were not for one thing.”

“And what is that, Holmes?”

“The finding of the pistol in her wardrobe.”

“Dear me, Holmes!” I cried, “that seemed to me to be the most damning incident of all.”

“Not so, Watson. It had struck me even at my first perfunctory reading as very strange, and now that I am in closer touch with the case it is my only firm ground for hope. We must look for consistency. Where there is a want of it we must suspect deception.”

“I hardly follow you.”

“Well now, Watson, suppose for a moment that we visualize you in the character of a woman who, in a cold, premeditated fashion, is about to get rid of a rival. You have planned it. A note has been written. The victim has come. You have your weapon. The crime is done. It has been workmanlike and complete. Do you tell me that after carrying out so crafty a crime you would now ruin your reputation as a criminal by forgetting to fling your weapon into those adjacent reed-beds which would forever cover it, but you must needs carry it carefully home and put it in your own wardrobe, the very first place that would be searched? Your best friends would hardly call you a schemer, Watson, and yet I could not picture you doing anything so crude as that.”

“In the excitement of the moment?”

“No, no, Watson, I will not admit that it is possible. Where a crime is coolly premeditated, then the means of covering it are coolly premeditated also. I hope, therefore, that we are in the presence of a serious misconception.”
