"Until 10.45 Lord Arthur was playing cards; a quarter of an hour later the police were on the scene, and the murder had been committed. In the meanwhile Colonel McIntosh's evidence proved conclusively that the accused had been sitting with him, smoking a cigar. It was obvious, therefore, clear as daylight, concluded the great lawyer, that his client was entitled to a full discharge; nay, more, he thought that the police should have been more careful before they harrowed up public feeling by arresting a high-born gentleman on such insufficient evidence as they had brought forward. "The question of the knife remained certainly, but Sir Marmaduke passed over it with guarded eloquence, placing that strange question in the category of those inexplicable coincidences which tend to puzzle the ablest detectives, and cause them to commit such unpardonable blunders as the present one had been. After all, the footman may have been mistaken. The pattern of that knife was not an exclusive one, and he, on behalf of his client, flatly denied that it had ever belonged to him. "Well," continued the man in the corner, with the chuckle peculiar to him in moments of excitement, "the noble prisoner was discharged. Perhaps it would be invidious to say that he left the court without a stain on his character, for I daresay you know from experience that the crime known as the York Mystery has never been satisfactorily cleared up. "Many people shook their heads dubiously when they remembered that, after all, Charles Lavender was killed with a knife which one witness had sworn belonged to Lord Arthur; others, again, reverted to the original theory that George Higgins was the murderer, that he and James Terry had concocted the story of Lavender's attempt at blackmail on Lord Arthur, and that the murder had been committed for the sole purpose of robbery. "Be that as it may, the police have not so far been able to collect sufficient evidence against Higgins or Terry, and the crime has been classed by press and public alike in the category of so-called impenetrable mysteries." CHAPTER IX A BROKEN-HEARTED WOMAN The man in the corner called for another glass of milk, and drank it down slowly before he resumed: "Now Lord Arthur lives mostly abroad," he said. "His poor, suffering wife died the day after he was liberated by the magistrate. She never recovered consciousness even sufficiently to hear the joyful news that the man she loved so well was innocent after all. "Mystery!" he added as if in answer to Polly's own thoughts. "The murder of that man was never a mystery to me. I cannot understand how the police could have been so blind when every one of the witnesses, both for the prosecution and defence, practically pointed all the time to the one guilty person. What do you think of it all yourself?" "I think the whole case so bewildering," she replied, "that I do not see one single clear point in it."
