“It is a queer case,” said I. “The circumstantial evidence seems to be strongly against Miss Dalby, but it is manifestly improbable that she murdered the man.” “It seems so,” he agreed. “But the case will be decided on the evidence; and the evidence will be considered by a judge, not by a Home Secretary. You notice the importance of Burnham’s destination?” “Yes. He was evidently dead when the train arrived at Holmwood. But it isn’t clear how long he had been dead.” “The evidence,” said Thorndyke, “points strongly to the tunnel between Cawden and Holmwood as the place where the murder was committed. You will remember that the up-express passed our train in the tunnel. If the adjoining compartments were empty, the sound of a pistol shot would be completely drowned by the noise of the express thundering past. Then you will remember the fragments of the electric bulb that we picked up, and that there was no light on in the carriage. That is rather significant. It not only suggests that the crime was committed in the dark, but there is a distinct suggestion of preparation--arrangement and premeditation. It suggests that the murderer knew what the circumstances would be and provided for them.” “Yes; and that is rather a point against our client. But I don’t quite see what you expect to get out of that sheet of the letter. It is the presence of the letter, rather than its matter, that constitutes the evidence against Miss Dalby.” “I don’t expect to learn anything from it,” replied Thorndyke; “but the letter will be the prosecution’s trump card, and it is always well to know in advance exactly what cards your opponent holds. It is a mere matter of routine to examine everything, relevant or irrelevant.” The inquest was to be held at Densford on the third day after the discovery of the body. But in the interval certain new facts had come to light. One was that the deceased was conveying to the Holmwood branch of the bank a sum of three thousand pounds, of which one thousand was in gold and the remainder in Bank of England notes, the whole being contained in a leather handbag. This bag had been found, empty, in a ditch by the side of the road which led from the station to the house of Miss Carleigh, the Vice-President of the Women’s Emancipation League. It was further stated that the ticket-collector at Holmwood had noticed that Miss Dalby--whom he knew by sight--was carrying a bag of the kind described when she passed the barrier, and that when she returned, about an hour later, she had no bag with her. On the other hand, Miss Carleigh had stated that the bag which Miss Dalby brought to her house was her (Miss Carleigh’s) property, and she had produced it for the inspection of the police. So that already there was some conflict of evidence, with a balance distinctly against Miss Dalby.
