If this hypothesis were correct, and someone was with Dr. Lana before Mrs. Madding met Mr. Arthur Morton, then who was this someone, and what motives had he for wishing evil to the doctor?  It was universally admitted that if the friends of the accused could throw light upon this, they would have gone a long way towards establishing his innocence.  But in the meanwhile it was open to the public to say—­as they did say—­that there was no proof that anyone had been there at all except the young squire; while, on the other hand, there was ample proof that his motives in going were of a sinister kind.  When Mrs. Madding called, the doctor might have retired to his room, or he might, as she thought at the time, have gone out and returned afterwards to find Mr. Arthur Morton waiting for him.  Some of the supporters of the accused laid stress upon the fact that the photograph of his sister Frances, which had been removed from the doctor’s room, had not been found in her brother’s possession.  This argument, however, did not count for much, as he had ample time before his arrest to burn it or to destroy it.  As to the only positive evidence in the case—­the muddy footmarks upon the floor—­they were so blurred by the softness of the carpet that it was impossible to make any trustworthy deduction from them.  The most that could be said was that their appearance was not inconsistent with the theory that they were made by the accused, and it was further shown that his boots were very muddy upon that night.  There had been a heavy shower in the afternoon, and all boots were probably in the same condition.

Such is a bald statement of the singular and romantic series of events which centred public attention upon this Lancashire tragedy.  The unknown origin of the doctor, his curious and distinguished personality, the position of the man who was accused of the murder, and the love affair which had preceded the crimes all combined to make the affair one of those dramas which absorb the whole interest of a nation.  Throughout the three kingdoms men discussed the case of the Black Doctor of Bishop’s Crossing, and many were the theories put forward to explain the facts; but it may safely be said that among them all there was not one which prepared the minds of the public for the extraordinary sequel, which caused so much excitement upon the first day of the trial, and came to a climax upon the second.  The long files of the Lancaster Weekly with their report of the case lie before me as I write, but I must content myself with a synopsis of the case up to the point when, upon the evening of the first day, the evidence of Miss Frances Morton threw a singular light upon the case.
