It was no very difficult undertaking for a man like Douglas Croft to satisfy the police that anything which had happened in Lukin’s factory during the course of the last few hours was perfectly correct, and in the ordinary course of every-day events, and that the only plan now to be adopted was to send for a locksmith, have a new fastening put upon the gates, and the needful repairs in the wood-work effected without delay. Neither did he experience any greater trouble in making the doctor understand that there was something which had preceded the attempt at suicide, and which it was desirable on all accounts to attribute to temporary insanity. “Whether he live or die,” finished Mr. Croft, “and, in my opinion, it matters very little which he does, this freak must be regarded as that of a lunatic. Meantime, if you have no objection to meeting my friend Mr. Rymner Henry, I think it might be a satisfaction to Mrs. Dudley to know you have had a consultation.” In reply to which speech, Doctor Milworth, bowing low, expressed himself to the effect, that he had no objection whatever to meeting Mr. Henry—that he should like to meet him, in fact, which may seem the less astonishing, perhaps, when it is explained, that during the entire time Doctor Milworth took charge of the case, he was in the habit of going about among his other patients, watch in hand, and casually remarking he was rather in a hurry to-day, because he had to meet Mr. Rymner Henry at a quarter past two, or a quarter to five, or four precisely, according to the hour mentioned by that celebrated surgeon, “in consultation on a most important case.” Why Mr. Croft considered it necessary to send for further advice, he himself perhaps could not very clearly have told, for he knew that if Arthur Dudley were to live, Dr. Milworth had done everything which could be done towards compassing that object. Possibly he might have some idea of thereby winning the doctor’s greater confidence, ensuring his greater secrecy, for already Douglas Croft held in his hand a letter which he believed would prove a clue to all this mystery. It was from Mr. Lukin, stating that on the 23rd he should be in London to _inspect the books_. “That is the secret, then,” thought Douglas Croft; “before you inspect the books, though, Mr. Lukin, I will take a look at them myself. I do not think there will be much difficulty in unravelling the skein; I am greatly mistaken if he possessed brains sufficient to cook his accounts, and perhaps for that very reason he may have got them into a confounded mess.” When Mr. Croft, however, tried to pass into the office he failed to do so, by reason of the piles of shavings and other combustible materials which stopped the entrance. “I want a reliable man, Mrs. Dudley,” he said, returning to her; “a man who can be trusted to hold his tongue, if he be paid for doing so. Is there amongst the workpeople such a treasure to be found?”
