The hound of death

"What - what are you doing?" gasped Mr Dinsmead. His face had gone chalky-white, the purple dying out as if by magic. Mrs Dinsmead gave a thin, high, frightened cry.

"You read the papers, Mr Dinsmead? I am sure you do. Sometimes one reads accounts of a whole family being poisoned - some of them recover, some do not. In this case, one would not. The first explanation would be the tinned brawn you were eating, but supposing the doctor to be a suspicious man, not easily taken in by the tinned food theory? There is a packet of arsenic in your larder. On the shelf below it is a packet of tea. There is a convenient hole in the top shelf. What more natural to suppose than that the arsenic found its way into the tea by accident? Your son Johnnie might be blamed for carelessness, nothing more."

"I - I don't know what you mean," gasped Dinsmead.

"I think you do." Mortimer took up a second teacup and filled a second test-tube. He fixed a red label to one and a blue label to the other.

"The red-labeled one," he said, "contains tea from your daughter Charlotte's cup, the other from your daughter Magdalen's. I am prepared to swear that in the first I shall find four or five times the amount of arsenic than in the latter."

"You are mad!" said Dinsmead.

"Oh, dear me, no. I am nothing of the kind. You told me today, Mr Dinsmead, that Magdalen was not your own daughter. You lied to me. Magdalen is your daughter. Charlotte was the child you adopted, the child who was so like her mother that when I held a miniature of that mother in my hand today I mistook it for one of Charlotte herself. You wanted your own daughter to inherit the fortune, and since it might be impossible to keep Charlotte out of sight, and someone who knew her mother might have realized the truth of the resemblance, you decided on, well - sufficient white arsenic at the bottom of a teacup."

Mrs Dinsmead gave a sudden high cackle, rocking herself to and fro in violent hysterics.

"Tea," she squeaked, "that's what he said, tea, not lemonade."

"Hold your tongue, can't you?" roared her husband wrathfully.

Mortimer saw Charlotte looking at him, wide-eyed, wondering, across the table. Then he felt a hand on his arm, and Magdalen dragged him out of earshot.

"Those," she pointed at the phials - "Daddy. You won't -"

Mortimer laid his hand on her shoulder. "My child," he said, "you don't believe in the past. I do. I believe in the atmosphere of this house. If he had not come to this particular house, perhaps - I say perhaps - your father might not have conceived the plan he did. I will keep these two test-tubes to safeguard Charlotte now and in the future. Apart from that, I shall do nothing - in gratitude, if you will, to the hand that wrote S.O.S."

"Above all, avoid worry and excitement," said Dr Meynell, in the comfortable fashion affected by doctors.

Mrs Harter, as is often the case with people hearing these soothing but meaningless words, seemed more doubtful than relieved.

"There is a certain cardiac weakness," continued the doctor fluently, "but nothing to be alarmed about. I can assure you of that. All the same," he added, "it might be as well to have an elevator installed. Eh? What about it?"

Mrs Harter looked worried.

Dr Meynell, on the contrary, looked pleased with himself. The reason he liked attending rich patients rather than poor ones was that he could exercise his active imagination in prescribing for their ailments.

"Yes, an elevator," said Dr Meynell, trying to think of something else even more dashing - and failing. "Then we shall avoid all undue exertion. Daily exercise on the level on a fine day, but avoid walking up hills. And, above all, plenty of distraction for the mind. Don't dwell on your health."

To the old lady's nephew, Charles Ridgeway, the doctor was slightly more explicit.

"Do not misunderstand me," he said. "Your aunt may live for years, probably will. At the same time, shock or overexertion might carry her off like that!" He snapped his fingers. "She must lead a very quiet life. No exertion. No fatigue. But, of course, she must not be allowed to brood. She must be kept cheerful and the mind well distracted."

"Distracted," said Charles Ridgeway thoughtfully.

Charles was a thoughtful young man. He was also a young man who believed in furthering his own inclinations whenever possible.

That evening he suggested the installation of a radio set.

Mrs Harter, already seriously upset at the thought of the elevator, was disturbed and unwilling. Charles was persuasive.

"I do not know that I care for these new-fangled things," said Mrs Harter piteously. "The waves, you know - the electric waves. They might affect me."

Charles, in a superior and kindly fashion, pointed out the futility of this idea.

Mrs Harter, whose knowledge of the subject was of the vaguest but who was tenacious of her own opinion, remained unconvinced.
