On the evening of the first of those days Detective Griffiths received, through the trustworthy post-boy, the following brief note from her:
I have found out that Hales owed Sandy close upon a hundred pounds, which he had borrowed at various times.
I don’t know whether you will think this fact of any importance.
L.B.
Mr. Griffiths repeated the last sentence blankly. “If Harry Craven were put upon his defence, his counsel, I take it, would consider the fact of first importance,” he muttered. And for the remainder of that day Mr. Griffiths went about his work in a perturbed state of mind, doubtful whether to hold or to let go his theory concerning Harry Craven’s guilt.
The next morning there came another brief note from Loveday which ran thus:
As a matter of collateral interest, find out if a person, calling himself Harold Cousins, sailed two days ago from London Docks for Natal in the Bonnie Dundee?
To this missive, Loveday received, in reply, the following somewhat lengthy dispatch:
I do not quite see the drift of your last note, but have wired to our agents in London to carry out its suggestion. On my part, I have important news to communicate. I have found out what Harry Craven’s business out of doors was on the night of the murder, and at my instance a warrant has been issued for his arrest. This warrant it will be my duty to serve on him in the course of today. Things are beginning to look very black against him, and I am convinced his illness is all a sham. I have seen Waters, the man who is supposed to be attending him, and have driven him into a corner and made him admit that he has only seen young Craven once – on the first day of his illness – and that he gave his certificate entirely on the strength of what Mrs. Craven told him of her son’s condition. On the occasion of this, his first and only visit, the lady, it seems, also told him that it would not be necessary for him to continue his attendance, as she quite felt herself competent to treat the case, having had so much experience in fever cases among the blacks at Natal.
