Now if that is all for the present....”
“I fear, my lord, that it is not nearly all.”
The tone of this stung our host.
“Mr Holmes! On the recommendation of a close friend I have invited you to investigate a most sensitive family matter. You now inquire into things which I cannot see are in the least necessary. I am anxious to benefit from your advice but I am bound to say that there is a point beyond which I shall feel compelled to do without it!”
Holmes did not even blink.
“I trust not, my lord, for if I am compelled to relinquish the case, the advice which you will receive is likely to be that of the Metropolitan Police. Most probably, as matters stand, it will come in the person of Chief Inspector Lestrade or Inspector Tobias Gregson, both of the Criminal Investigation Division of Scotland Yard. My lord, I cannot afford to be party to compounding a felony.”
It is a cliché to say that a man looks stunned but that was exactly how Lord Blagdon appeared. Holmes allowed him no retreat.
“I have to tell you, Lord Blagdon, that the bonbonnière before you contains two deposits of melted chocolate or something of the kind. One of these, in my opinion, contained a lethal dose of Aconitum ferox, the most deadly and still one of the most secret of all poisons.”
“Stuff and nonsense! Balderdash!”
I had expected Lord Blagdon to be further stunned by this news but he came out fighting, as the saying is. Even Holmes paused and this gave me the chance to intervene between them.
“Since I am a medical man, Lord Blagdon, it may help us all if you can tell me quite simply how Lady Clementina died.”
He almost laughed at me.
“Quite simply, she died of heart failure at an advanced age, sir! Though she put on a brave face and went out and about as much as she could, she had been ailing for years. It was not unusual at her time of life. The wonder is she lived as long as she did. I have served in India with the 17th Lancers and I too know a little of vengeance by secret poison. I have some notion of what the symptoms are. She did not exhibit them.”
He turned away to the window, as if to conceal from us his exasperation. Then he swung round again with a spin of the hem of his morning coat and a wagging finger.
“Suspect me, if you like! I was present when Lady Clem died and I can tell you that she died of heart failure. Her final illness lasted for more than a week. During that time the bonbon dish you refer to was never within her reach and, believe me, she had no use for it during her last days. The Duchess of Paisley visited her just before the end and took dinner in Lady Clementina’s room. The poor old woman could manage nothing apart from broth and plain water. Her physician, Sir Matthew Reid, and a nurse were in constant attendance. A man of Sir Matthew’s eminence may be allowed, I think, to know the difference between heart failure and acute poisoning. Your suggestions are quite preposterous!”
“Lord Arthur ...” Holmes began, but he got no further.
“I have already told you, Mr Holmes, that Lord Arthur was several hundred miles away. You or your friends at Scotland Yard may check for yourselves that he was staying at Danielli’s Hotel in Venice. When he was not at the hotel, he was yachting on the Adriatic or with a shooting party in the Pinetum, accompanied by at least a dozen witnesses. As for having a motive to murder, that is the most absurd thing of all. He would not benefit by her death and he knew it. Her intentions were never in doubt. I grant you Lord Arthur benefited a little in the end—only because after her death I asked that I should not have certain items she bequeathed to me. Lord Arthur did not know beforehand that this would happen. Despite your reputation, if this is the best you can do, Mr Holmes....”
“Perhaps it would help,” I said, with some sense of desperation, “if you could tell me what happened to the contents of the bonbon dish.”
“The dish was
