"What price was she to pay for them?"

"Price!"

"You didn't expect Seligmann to give them up for nothing?"

"He wanted her to go on tour, I believe, instead of bringing her out in town, as he had half promised to do."

"It was natural perhaps that your future wife should be willing to make a sacrifice for your sake."

"It was hardly a sacrifice. She is not good enough for the London stage. Besides, I am not engaged to her. Friendship is----"

"I warrant she considers herself engaged to you."

"I cannot help that."

"Of course not," said the professor, "but you were glad enough to get the papers. May I look at the envelope they came in?"

"I destroyed it," Marsh replied to my utter astonishment.

"That is a pity. If Miss Wickham says she did not get those papers, it will be awkward for you. Could you swear the writing on the envelope was hers?"

"They could have come from no one else."

"And you think she murdered Seligmann to get them?"

"I am not to be trapped into admitting anything of the sort."

"As you will, Mr. Marsh. For my part, I expect this affair will open Miss Wickham's eyes to your--your true worth."

And Quarles took up his hat and walked out of the room. I followed him. In the street he took off his gla.s.ses and put them in his pocket.

They were the same he had worn that morning--a pair he did not often use.

"The Honorable Percival Marsh is a worm," he remarked.

"Now for Miss Wickham," said I.

"There is no necessity to see her," said Quarles. "I dare say it is true what this worm says. She went to offer her talent cheap to Seligmann on condition that he would give her the papers. I can guess what happened. They talked over the bargain, but Seligmann refused to do what she wanted, and was able, probably, to show her that Marsh was a worthless scoundrel. Unless something of this sort had happened she would have written to Marsh to tell him she had been unsuccessful. I have little doubt Seligmann treated her in a fatherly manner, and then let her out through the garden, perhaps because he found the light in the hall was out. He returned to find--I am not sure yet what it was he found in his study, but nothing to alarm him, I am sure. To-morrow we will go to Maidenhead, Wigan, and see what servants are at the cottage."

At noon next day we were in Maidenhead.

There was a yard and coach house somewhat removed from the house, and a chauffeur was cleaning a car. In the corner of the yard lay a large dog of the boar-hound type, but I have never seen one quite like it before.

"Is that dog savage?" Quarles asked.

"He doesn't like strangers, as a rule," said the man, "but he's ill."

"Foreign breed of dog, eh?" said Quarles, entering the yard.

"Came from Russia."

The professor looked puzzled. It was evident that something interfered with his theory.

"Sorry to disturb you," he went on, "but we've come to ask a few questions about the awful circ.u.mstances of your master's death."

"You're right, it is awful," said the man. "The mistress will go mad, that's what she'll do. I shouldn't have been surprised if she'd chucked herself out of the car as we came down this morning."

"She has returned to the cottage, then? I suppose it was you who drove her up yesterday?"

"Yes, and on Sat.u.r.day I drove them both up as far as Colnbrook, and then something went wrong with the car. They had to go on by train."

"How did she arrive home on Sunday morning, then?"

"In a taxi."

"And what did she do on Sunday?"

"Had out the punt and went up to Boulter's, where she would be certain to meet a lot of friends. I dare say you know the mistress is a famous dancer. That kind of people are a bit unconventional."

"Do you happen to know the Honorable Percival Marsh?" asked Quarles.

"Yes. He's been here, but not lately. The mistress lunches with him in town sometimes. She seems to think more of him than I do. There's nothing in it. I've heard her laugh at him with the master."

"Is that the only dog about the place?" said Quarles.

"Yes. He's a pet; usually goes up to the opera with the mistress. He went on Sat.u.r.day, and came back like that on Sunday. He snapped at her in a frightened way when she came in here in the morning and got a hiding for it. I was afraid he'd go for her."

Quarles gave a short exclamation underneath his breath, and then he said in rather an agitated way: "Well go in and see Mrs. Seligmann, Wigan." And as we left the yard he went on: "You must make the servant show us in to her mistress without announcing us. We must take Mrs.

Seligmann unawares."

The servant proved difficult to persuade, and I had to explain who I was before she yielded. Mrs. Seligmann sprang from the sofa as we entered. She looked wild, almost mad, as the chauffeur had said, but she recognized us and forced herself to welcome us.

"What are you here for?" she said, and I started. There was the suggestion of a snarl in her voice.

"We believe your husband was murdered by Percival Marsh," said Quarles quietly.

"It's a lie!" she shrieked.

"How comes it, then, that he has those papers which were in your husband's possession?"

In a moment she had hurled herself upon the professor, and had snapped at the hand which he threw out to protect himself. Her strength was awful, and all the time we were struggling with her she fought with her nails and teeth, and growled like an infuriated animal. Her clothes were partly torn from her in the struggle, and--but it was too ghastly to enlarge upon. She was an animal in the form of a beautiful woman. The house was quickly roused, and we had to have the chauffeur's help before we could bind her securely. Then I telephoned to Maidenhead for the police.

"I thought a dog had helped, Wigan; that was my theory," said Quarles as we went back to town. "I noted that a dog had trodden on the polished skirting near the study sofa. Miss Wickham might have had a dog, that is why I questioned the housemaid so closely to make sure she entered the house quite alone. When we were brought in contact with Marsh I suspected Mrs. Seligmann. Those gla.s.ses I wear sometimes are curious, acting like opera-gla.s.ses, and they enabled me to see a portrait of Mrs. Seligmann standing back on a corner table, and, moreover, that it was signed. Marsh evidently knew her well; was in love with her, perhaps, and she with him. My saying that he had first been to River Mansions in the morning was guesswork, but by his not denying it, the fact was established that the papers must have come into his possession, or why should he have gone there? He must have known that Miss Wickham usually went away on Sat.u.r.day or Sunday and did not return till late on Monday. I argued that Mrs. Seligmann might have sent them, and that Marsh suspected this, hence his visit to Miss Wickham to make certain. It may be true that he did not know she was going to Seligmann on Sat.u.r.day night, and if he heard from the porter that she had left town on Sat.u.r.day afternoon he would know that the papers could not have come from her. He would hear from the porter that she had returned in the small hours of Sunday morning, and when, later in the day, he read of the murder he would not know what to think. It is also possible, Wigan, that Seligmann expected his wife to call for him that night. That their motor had broken down on the way up to town makes it even probable. I went to Maidenhead to see if Mrs.

Seligmann had a dog, a savage brute who would attack at her command, savage but small. The great brute in the yard did not fit my theory.

G.o.d knows I didn't suspect the real truth. Strange that I should have felt that I was in a forest, stranger still that Zena should speak of Pan. I don't explain, Wigan, I can't, but it has happened--a return of the human to wild and awful atavism. She meant to kill, to rid herself of the man who was in her way. The human in her used the stiletto or hatpin, the animal in her used claws. She will be called mad, and so she is in one sense, but not in another; nor was it murder in the true sense of the word. The wild wolf does not murder; he kills because he must. Even the dog recognized an enemy of whom he was afraid. The beast was not ill, but cowed, and snapped at her as you heard the chauffeur say. Had she had her way with me to-day, I should have looked like poor Seligmann."

Arriving in town I found that Miss Wickham had communicated with the police and had given an account of her visit to Hampstead, which closely corresponded with Quarles's idea. She had gone at that hour because she was anxious on Marsh's account, and it was the only time Seligmann could see her unless she waited another week. He was very kind, and had told her that Marsh was a scoundrel. He was attempting to make love to his wife, he declared, who laughed at him, and was quite in agreement with her husband when he said he would presently punish him by using the papers he held. He was expecting his wife to call for him that night in a taxi. She came, and killed him.

I am thankful to say that a fortnight after her arrest Mrs. Seligmann died.
