"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 glasses I wear sometimes are curious, acting like opera-glasses, 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 Saturday 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 Saturday night, and if he heard from the porter that she had left town on Saturday 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. God 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.
CHAPTER XV
THE STRANGE AFFAIR OF THE FLORENTINE CHEST
Only the other day, in a turning off Finsbury Pavement, there was demolished one of those anachronisms which used to be met with more frequently in London, an old house sandwiched in between immense blocks of buildings, a relic of the past holding its own against the commercial necessities and rush of modern civilization. It was connected with a very strange case Quarles and I had to deal with not long after the Seligmann affair.
