“It was Mr. Graham himself who had been the first to put the Procurator Fiscal in possession of the fact that the accused had written to David from London, breaking off her engagement. This information had, no doubt, directed the attention of the Fiscal to Miss Crawford, and the police soon brought forward the evidence which had led to her arrest.
“We had a final sensation on the third day, when Mr. Campbell, jeweller, of High Street, gave his evidence. He said that on October 25th a lady came to his shop and offered to sell him a pair of diamond earrings. Trade had been very bad, and he had refused the bargain, although the lady seemed ready to part with the earrings for an extraordinarily low sum, considering the beauty of the stones.
“In fact it was because of this evident desire on the lady’s part to sell at any cost that he had looked at her more keenly than he otherwise would have done. He was now ready to swear that the lady that offered him the diamond earrings was the prisoner in the dock.
“I can assure you that as we all listened to this apparently damnatory evidence, you might have heard a pin drop amongst the audience in that crowded court. The girl alone, there in the dock, remained calm and unmoved. Remember that for two days we had heard evidence to prove that old Dr. Crawford had died leaving his daughter penniless, that having no mother she had been brought up by a maiden aunt, who had trained her to be a governess, which occupation she had followed for years, and that certainly she had never been known by any of her friends to be in possession of solitaire diamond earrings.
“The prosecution had certainly secured an ace of trumps, but Sir James Fenwick, who during the whole of that day had seemed to take little interest in the proceedings, here rose from his seat, and I knew at once that he had got a titbit in the way of a ‘point’ up his sleeve. Gaunt, and unusually tall, and with his beak-like nose, he always looks strangely impressive when he seriously tackles a witness. He did it this time with a vengeance, I can tell you. He was all over the pompous little jeweller in a moment.
“ ‘Had Mr. Campbell made a special entry in his book, as to the visit of the lady in question?’
“ ‘No.’
“ ‘Had he any special means of ascertaining when that visit did actually take place?’
“ ‘No—but—’
“ ‘What record had he of the visit?’
“Mr. Campbell had none. In fact, after about twenty minutes of cross-examination, he had to admit that he had given but little thought to the interview with the lady at the time, and certainly not in connection with the murder of Lady Donaldson, until he had read in the papers that a young lady had been arrested.
“Then he and his clerk talked the matter over, it appears, and together they had certainly recollected that a lady had brought some beautiful earrings for sale on a day which must have been the very morning after the murder. If Sir James Fenwick’s object was to discredit this special witness, he certainly gained his point.
“All the pomposity went out of Mr. Campbell, he became flurried, then excited, then he lost his temper. After that he was allowed to leave the court, and Sir James Fenwick resumed his seat, and waited like a vulture for its prey.
“It presented itself in the person of Mr. Campbell’s clerk, who, before the Procurator Fiscal, had corroborated his employer’s evidence in every respect. In Scotland no witness in any one case is present in court during the examination of another, and Mr. Macfarlane, the clerk, was, therefore, quite unprepared for the pitfalls which Sir James Fenwick had prepared for him. He tumbled into them, head foremost, and the eminent advocate turned him inside out like a glove.
“Mr. Macfarlane did not lose his temper; he was of too humble a frame of mind to do that, but he got into a hopeless quagmire of mixed recollections, and he too left the witness-box quite unprepared to swear as to the day of the interview with the lady with the diamond earrings.
“I dare say, mind you,” continued the man in the corner with a chuckle, “that to most people present, Sir James Fenwick’s cross-questioning seemed completely irrelevant. Both Mr. Campbell and his clerk were quite ready to swear that they had had an interview concerning some diamond earrings with a lady, of whose identity with the accused they were perfectly convinced, and to the casual observer the question as to the time or even the day when that interview took place could make but little difference in the ultimate issue.
“Now I took in, in a moment, the entire drift of Sir James Fenwick’s defence of Edith Crawford. When Mr. Macfarlane left the witness-box, the second victim of the eminent advocate’s caustic tongue, I could read as in a book the whole history of that crime, its investigation, and the mistakes made by the police first and the Public Prosecutor afterwards.
“Sir James Fenwick knew them, too, of course, and he placed a finger upon each one, demolishing—like a child who blows upon a house of cards—the entire scaffolding erected by the prosecution.
“Mr. Campbell’s and Mr. Macfarlane’s identification of the accused with the lady who, on some date—admitted to be uncertain—had tried to sell a pair of diamond earrings, was the first point. Sir James had plenty of witnesses to prove that on the 25th, the day after the murder, the accused was in London, whilst, the day before, Mr. Campbell’s shop had been closed long before the family circle had seen the last of Lady Donaldson. Clearly the jeweller and his clerk must have seen some other lady, whom their vivid imagination had pictured as being identical with the accused.
“Then
