"Now I come to Helene Vauquier’s second mistake. On the evening when you saw Mlle. Celie in the garden behind the baccarat-rooms you noticed that she wore no jewellery except a pair of diamond eardrops. In the photograph of her which Wethermill showed me, again she was wearing them. Is it not, therefore, probable that she usually wore them? When I examined her room I found the case for those earrings-the case was empty. It was natural, then, to infer that she was wearing them when she came down to the seance."
"Yes."
"Well, I read a description-a carefully written description-of the missing girl, made by Helene Vauquier after an examination of the girl’s wardrobe. There is no mention of the earrings. So I asked her-'Was she not wearing them?' Helene Vauquier was taken by surprise. How should I know anything of Mlle. Celie’s earrings? She hesitated. She did not quite know what answer to make. Now, why? Since she herself dressed Mile. Celie, and remembers so very well all she wore, why does she hesitate? Well, there is a reason. She does not know how much I know about those diamond eardrops. She is not sure whether we have not dipped into that pot of cold cream and found them. Yet without knowing she cannot answer. So now we come back to our pot of cold cream."
"Yes!" cried Mr. Ricardo. "They were there."
"Wait a bit," said Hanaud. "Let us see how it works out. Remember the conditions. Vauquier has some small thing which she must hide, and which she wishes to hide in Mlle. Celie’s room. For she admitted that it was her suggestion that she should look through mademoiselle’s wardrobe. For what reason does she choose the girl’s room, except that if the thing were discovered that would be the natural place for it? It is, then, something belonging to Mlle. Celie. There was a second condition we laid down. It was something Vauquier had not been able to hide before. It came, then, into her possession last night. Why could she not bide it last night? Because she was not alone. There were the man and the woman, her accomplices. It was something, then, which she was concerned in hiding from them. It is not rash to guess, then, that it was some piece of the plunder of which the other two would have claimed their share-and a piece of plunder belonging to Mlle. Celie. Well, she has nothing but the diamond eardrops. Suppose Vauquier is left alone to guard Mlle. Celie while the other two ransack Mme. Dauvray’s room. She sees her chance. The girl cannot stir hand or foot to save herself. Vauquier tears the eardrops in a hurry from her ears-and there I have my drop of blood just where I should expect it to be. But now follow this! Vauquier hides the earrings in her pocket. She goes to bed in order to be chloroformed. She knows that it is very possible that her room will be searched before she regains consciousness, or before she is well enough to move. There is only one place to hide them in, only one place where they will be safe. In bed with her. But in the morning she must get rid of them, and a nurse is with her. Hence the excuse to go to Mlle. Celie’s room. If the eardrops are found in the pot of cold cream, it would only be thought that Mlle. Celie had herself hidden them there for safety. Again it is conjecture, and I wish to make sure. So I tell Vauquier she can go away, and I leave her unwatched. I have her driven to the depot instead of to her friends, and searched. Upon her is found the pot of cream, and in the cream Mlle. Celie’s eardrops. She has slipped into Mlle. Celie’s room, as, if my theory was correct, she would be sure to do, and put the pot of cream into her pocket. So I am now fairly sure that she is concerned in the murder."
"We then went to Mme. Dauvray’s room and discovered her brilliants and her ornaments. At once the meaning of that agitated piece of hand-writing of Mlle. Celie’s becomes clear. She is asked where the jewels are hidden. She cannot answer, for her mouth, of course, is stopped. She has to write. Thus my conjectures get more and more support. And, mind this, one of the two women is guilty-Celie or Vauquier. My discoveries all fit in with the theory of Celie’s innocence. But there remain the footprints, for which I found no explanation."
"You will remember I made you all promise silence as to the finding of Mme. Dauvray’s jewellery. For I thought, if they have taken the girl away so that suspicion may fall on her and not on Vauquier, they mean to dispose of her. But they may keep her so long as they have a chance of finding out from her Mme. Dauvray’s hiding-place. It was a small chance but our only one. The moment the discovery of the jewellery was published the girl’s fate was sealed, were my theory true."
"Then came our advertisement and Mme. Gobin’s written testimony. There was one small point of interest which I will take first: her statement that Adele was the Christian name of the woman with the red hair, that the old woman who was the servant in that house in the suburb of Geneva called her Adele, just simply Adele. That interested me, for Helene Vauquier had called her Adele too when she was describing to us the unknown visitor. 'Adele' was what Mme. Dauvray called her."
"Yes," said Ricardo. "Helene Vauquier made a slip there. She should have given her a false name."
Hanaud nodded.
