"I remember," Bruce Cardyn nodded. "Yes, we were fortunate enough to satisfy General Hetherington."
"But the General spoke of Messrs. Wilkins and Alleyn. I never heard him mention your name."
"I dare say not." Bruce Cardyn's smile deepened. "Yet I am the junior partner. My senior's name is Misterton. Wilkins and Alleyn is merely a—shall I say?—nom de plume. You see, if we visited you under our own names we should be more likely to be recognised by any professional crook who has read the list of private inquiry agents. If you will entrust your business to us, Lady Anne, I can promise that we will do our best for you."
"I believe you will. But it is no easy problem that I wish you to solve."
She stopped, and seemed for a moment to be really struggling for words in which to state her dilemma.
As Bruce Cardyn watched her the pity in his grey eyes grew and strengthened. There was something very pathetic about the stern old face, with the strong mouth that twitched every now and then, and the nameless dread looking out of the big shadowed eyes.
At last Lady Anne seemed to rally her courage by a supreme effort.
"Mr. Cardyn, I have never been a coward in my life—till now! And here to-day I am living in my own house, surrounded by servants, who have for the most part grown grey in my service, and by those who are bound to me by ties of blood and professed affection, yet—"
"Yet?" Bruce Cardyn echoed, a touch of surprise in his grey eyes.
Lady Anne looked at him, the faint colour that had come back to her withered cheeks ebbing once more; the dread in her eyes deepening. Her voice sank to a whisper:
"And yet, as I say, in my own house, surrounded by those I know and love, and who one would expect to have some sort of liking for me, some one is trying to kill me!"
It was not at all what Bruce Cardyn had expected to hear. He was silent for a minute. Sundry stories he had heard of old people who accused their own families of trying to murder them recurred to his mind, but Lady Anne was not old enough for that.
"You have some ground for your belief?" he hazarded at last.
Lady Anne bent her head.
"At first it was only a mere suspicion. I tried to smother it, to assure myself that it was only the merest fancy. I said to myself I am a disagreeable, snappy old woman, I know, but surely I am not so bad that anyone should wish to murder me. Now, however, conviction has been forced upon me. But, Mr. Cardyn, before we proceed, can you with as many underlings as you choose to bring, with any and every expense guaranteed, can you promise me safety in my own house?"
Bruce Cardyn's face was very grave. Lady Anne's aspect was so controlled, so direct, that the momentary suspicion that had flitted across his mind was dismissed finally and for ever.
"We will do our best to ensure your safety in every way, Lady Anne," he said steadily. "And I think we ought to succeed. More it is not in the power of mortal man to promise."
"It is not!" Lady Anne assented. "Well, Mr. Cardyn, I am going to trust you to safeguard me. Life is sweet to anyone, I suppose, even when one is old and lonely. And we all shrink from the great abyss. Now, as I tell you, my life is being attempted, has been attempted by some member of my household, as I believe, and I want you to discover who it is, and to prevent the crime. But, above all things, I do not want the regular police called in. I want the whole thing kept as quiet as possible. I know that this will make your work more difficult, but I hope you will be none the less willing to undertake it."
"Certainly we will undertake it," Bruce Cardyn promised, his face pale and grave. "But first can you can give some of the ground you have to go upon, Lady Anne?"
Lady Anne hesitated a minute, then she bent forward and took the pill-box again.
"I think this will show you best what I have to fear. Look!" She held the box toward him.
He put up a monocle and looked at its contents with great curiosity as it lay in his hand.
"The pills in that box originally were made up by the chemist I have employed for years, from a prescription given me by my own doctor. I was taking one the last thing every night. There were twelve in the box when it came. I took one at bed-time for five nights. I was glancing at them, only after I had taken the fifth; there were still eight left! What do you make of that?"
Mr. Cardyn looked at the pills; the gravity of his expression deepened.
"You are quite sure of your facts, Lady Anne. It would not be difficult, for instance, to make a mistake in the number of pills or of the number of nights you took them."
For answer, Lady Anne drew a small silver key from the handbag in front of her, and unlocked another small drawer. Inside was a sheet of embossed letter-paper. There were very few lines upon it, but the signature was one of the best known of the day:
DEAR LADY ANNE,
I have analysed the pills you sent me. Seven of them are harmless. The eighth contains hyoscine enough to kill ten women. I am returning them as you requested.
What can I do for you now? Please let me help you.
Yours always,
ROBERT SAINTSBURY.
"That," said Lady Anne very deliberately, "settles the question, I think!"
Chapter II
Bruce Cardyn put the box down. "It certainly does appear to settle the question that some one is attempting your life. But—pardon me—it proves nothing with regard to the would-be assassin being a member of your household."
"Do you not think so?" Lady Anne questioned coldly. "Since the pills were kept in a drawer in my bedroom, it is difficult to see how anyone, not a member of my household, could have access to them."
"Difficult," Bruce Cardyn assented, "but not impossible. And, in a case of this kind, we cannot afford to rule out any possibilities, Lady Anne. But, now, is this all you have to go upon?"
"I am sorry to say it is not." Lady Anne's pale blue eyes were mechanically watching the flickering of the leaves on a branch of the creeper that had strayed over her window. "I have had several curious accidents, but the most serious of them all, to my mind, is this. To begin with, it is my custom to take a glass of hot milk the last thing at night. For some time I have not been feeling very well—indigestion, I thought it to be—and took my usual simple remedies without success.
"I am not over fond of doctors, but was beginning to think I should have to consult my old friend, Dr. Spencer, when, one night as I was drinking my milk, I became conscious of a very curious taste. It set me thinking. I put the glass down, meaning to make inquiries, and went on with my reading. Half an hour later, when the milk had got cold, my pet Persian cat, climbing about as she does sometimes, got on the table by my side and lapped up some of it before noticed what she was doing. A very short time afterwards she was violently sick and lay writhing about in awful pain. I thought at first that she was going to die, but in the end got her round again. Since then I have taken no more hot milk. It goes down the drain, and I feel better. My indigestion is a thing of the past."
"And that is all?" Bruce Cardyn questioned.
"Is it not enough?" Lady Anne parried.
"It ought to be," Cardyn assented. "But, Lady Anne, have you no idea who is your would-be assassin?"
Lady Anne shook her head.
"None! Of course I do not say that my fancy has not strayed from one to another, and have said to myself—'it could not be so-and-so, it could not be so-and-so,' but of real knowledge, or even suspicion, I have none."
"I see."
There was
