On October 14 there had arrived in that city a weary, anxious-looking woman, with a girl and a little baby. They took a room at Geis's Hotel, registering as Mrs. Adams and daughter. Mrs. Adams seemed in great distress of mind, and never left her room.

The housekeeper, being shown their photographs, identified the woman and the girl as Mrs. Pitezel and her eldest daughter Dessie. As the same time there had been staying at another hotel in Detroit a Mr. and Mrs. Holmes, whose photographs showed them to be the Mr. Holmes in question and his third wife. These three parties—the two children, Mrs. Pitezel and her baby, and the third Mrs. Holmes—were all ignorant of each other's presence in Detroit; and under the secret guidance of Mr. Holmes the three parties (still unaware of their proximity to each other), left Detroit for Canada, arriving in Toronto on or about October 18, and registering at three separate hotels. The only one who had not to all appearances reached Toronto was the boy Howard.

In Toronto "Alice and Nellie Canning" stayed at the Albion Hotel.

They arrived there on October 19, and left on the 25th. During their stay a man, identified as Holmes, had called every morning for the two children, and taken them out; but they had come back alone, usually in time for supper. On the 25th he had called and taken them out, but they had not returned to supper. After that date Geyer could find no trace of them. Bearing in mind Holmes' custom of renting houses, he compiled a list of all the house agents in Toronto, and laboriously applied to each one for information. The process was a slow one, and the result seemed likely to be disappointing.

To aid his search Geyer decided to call in the assistance of the Press. The newspapers readily published long accounts of the case and portraits of Holmes and the children. At last, after eight days of patient and untiring investigation, after following up more than one false clue, Geyer received a report that there was a house—No. 16 St. Vincent Street—which had been rented in the previous October by a man answering to the description of Holmes. The information came from an old Scottish gentleman living next door. Geyer hastened to see him. The old gentleman said that the man who had occupied No. 16 in October had told him that he had taken the house for his widowed sister, and he recognised the photograph of Alice Pitezel as one of the two girls accompanying him. The only furniture the man had taken into the house was a bed, a mattress and a trunk. During his stay at No. 16 this man had called on his neighbour about four o'clock one afternoon and borrowed a spade, saying that he wanted to dig a place in the cellar where his widowed sister could keep potatoes; he had returned the spade the following morning. The lady to whom the house belonged recognised Holmes' portrait as that of the man to whom she had let No. 16.

At last Geyer seemed to be on the right track. He hurried back to St. Vincent Street, borrowed from the old gentleman at No. 18 the very spade which he had lent to Holmes in the previous October, and got the permission of the present occupier of No. 16 to make a search. In the centre of the kitchen Geyer found a trap-door leading down into a small cellar. In one corner of the cellar he saw that the earth had been recently dug up. With the help of the spade the loose earth was removed, and at a depth of some three feet, in a state of advanced decomposition, lay the remains of what appeared to be two children. A little toy wooden egg with a snake inside it, belonging to the Pitezel children, had been found by the tenant who had taken the house after Holmes; a later tenant had found stuffed into the chimney, but not burnt, some clothing that answered the description of that worn by Alice and Etta Pitezel; and by the teeth and hair of the two corpses Mrs. Pitezel was able to identify them as those of her two daughters. The very day that Alice and Etta had met their deaths at St. Vincent Street, their mother had been staying near them at a hotel in the same city, and later on the same day Holmes had persuaded her to leave Toronto for Ogdensburg. He said that they were being watched by detectives, and so it would be impossible for her husband to come to see her there.

But the problem was not yet wholly solved. What had become of Howard? So far Geyer's search had shown that Holmes had rented three houses, one in Cincinnati, one in Detroit, and one in Toronto. Howard had been with his sisters at the hotels in Indianapolis, and in Detroit the house agents had said that, when Holmes had rented a house there, he had been accompanied by a boy. Yet an exhaustive search of that house had revealed no trace of him. Geyer returned to Detroit and again questioned the house agents; on being pressed their recollection of the boy who had accompanied Holmes seemed very vague and uncertain. This served only to justify a conclusion at which Geyer had already arrived, that Howard had never reached Detroit, but had disappeared in Indianapolis. Alice's letters, written from there, had described how Holmes had wanted to take Howard out one day and how the boy had refused to stay in and wait for him. In the same way Holmes had called for the two girls at the Albion Hotel in Toronto on October 25 and taken them out with him, after which they had never been seen alive except by the old gentleman at No. 18 St. Vincent Street.

If Geyer could discover that Holmes had not departed in Indianapolis from his usual custom of renting houses, he might be on the high way to solving the mystery of Howard's fate. Accordingly he returned to Indianapolis.

In the meantime, Holmes, in his prison at Philadelphia, learnt of the discovery at Toronto. "On the morning of the 16th of July," he writes in his journal, "my newspaper was delivered to me about 8.30 a.m., and I had hardly opened it before I saw in large headlines the announcement of the finding of the children in Toronto. For the moment it seemed so impossible that I was inclined to think it was one of the frequent newspaper excitements that had attended the earlier part of the case, but, in attempting to gain some accurate comprehension of what was stated in the article, I became convinced that at least certain bodies had been found there, and upon comparing the date when the house was hired I knew it to be the same as when the children had been in Toronto; and thus being forced to realise the awfulness of what had probably happened, I gave up trying to read the article, and saw instead the two little faces as they had looked when I hurriedly left them—felt the innocent child's kiss so timidly given, and heard again their earnest words of farewell, and realised that I had received another burden to carry to my grave with me, equal, if not worse, than the horrors of Nannie Williams' death."

Questioned by the district attorney, Holmes met this fresh evidence by evoking once again the mythical Edward Hatch and suggesting that Miss Minnie Williams, in a "hellish wish for vengeance" because of Holmes' fancied desertion, and in order to make it appear probable that he, and not she, had murdered her sister, had prompted Hatch to commit the horrid deed. Holmes asked to be allowed to go to Toronto that he might collect any evidence which he could find there in his favour. The district attorney refused his request; he had determined to try Holmes in Philadelphia. "What more could, be said?" writes Holmes. Indeed, under the circumstances, and in the unaccountable absence of Edward Hatch and Minnie Williams, there was little more to be said.
