in New York raising capital for a company to exploit a new asphalt concession in the interior of Venezuela. Miss Laporte has also reappeared in New York as Mrs Ralston, with a mining claim in the mountains of Peru.’

‘And Templeton?’ asked Craig. ‘Had he had any previous matrimonial ventures?’

‘No, none. Of course he had had love affairs, mostly with the country-club set. He had known Miss Laporte pretty well, too, while he was in law school in New York. But when he settled down to work he seems to have forgotten all about the girls for a couple of years or so. He was very anxious to get ahead, and let nothing stand in his way. He was admitted to the bar and taken in by his father as junior member of the firm of Templeton, Mills & Templeton. Not long ago he was appointed a special master to take testimony in the get-rich-quick-company prosecutions, and I happen to know that he was making good in the investigation.’

Kennedy nodded. ‘What sort of fellow personally was Templeton?’ he asked.

‘Very popular,’ replied the district attorney, ‘both at the country club and in his profession in New York. He was a fellow of naturally commanding temperament – the Templetons were always that way. I doubt if many young men even with his chances could have gained such a reputation at thirty-five as his. Socially he was very popular, too, a great catch for all the sly mamas of the country club who had marriageable daughters. He liked automobiles and outdoor sports, and he was strong in politics, too. That was how he got ahead so fast.

‘Well, to cut the story short, Templeton met the Wainwright girls again last summer at a resort on Long Island. They had just returned from a long trip abroad, spending most of the time in the Far East with their father, whose firm has business interests in China. The girls were very attractive. They rode and played tennis and golf better than most of the men, and this fall Templeton became a frequent visitor at the Wainwright home in Williston.

‘People who know them best tell me that his first attentions were paid to Marian, a very dashing and ambitious young woman. Nearly every day Templeton’s car stopped at the house and the girls and some friend of Templeton’s in the country club went for a ride. They tell me that at this time Marian always sat with Templeton on the front seat. But after a few weeks the gossips – nothing of that sort ever escapes Williston – said that the occupant of the front seat was Laura. She often drove the car herself and was very clever at it. At any rate, not long after that the engagement was announced.’

As he walked up from the pretty little Williston station Kennedy asked: ‘One more question, Mr Whitney. How did Marian take the engagement?’

The district attorney hesitated. ‘I will be perfectly frank, Mr Kennedy,’ he answered. ‘The country-club people tell me that the girls were very cool toward each other. That was why I got that statement from Mrs Wainwright. I wish to be perfectly fair to everyone concerned in this case.’

We found the coroner quite willing to talk, in spite of the fact that the hour was late. ‘My friend, Mr Whitney, here, still holds the poison theory,’ began the coroner, ‘in spite of the fact that everything points absolutely toward asphyxiation. If I had been able to discover the slightest trace of illuminating-gas in the room I should have pronounced it asphyxia at once. All the symptoms accorded with it. But the asphyxia was not caused by escaping illuminating-gas.

‘There was an antique charcoal-brazier in the room, and I have ascertained that it was lighted. Now, anything like a brazier will, unless there is proper ventilation, give rise to carbonic oxide or carbon monoxide gas, which is always present in the products of combustion, often to the extent of from five to ten per cent. A very slight quantity of this gas, insufficient even to cause an odour in a room, will give a severe headache, and a case is recorded where a whole family in Glasgow was poisoned without knowing it by the escape of this gas. A little over one per cent of it in the atmosphere is fatal, if breathed for any length of time. You know, it is a product of combustion, and is very deadly – it is the much-dreaded white damp or afterdamp of a mine explosion.

‘I’m going to tell you a secret which I have not given out to the press yet. I tried an experiment in a closed room today, lighting the brazier. Some distance from it I placed a cat confined in a cage so it could not escape. In an hour and a half the cat was asphyxiated.’

The coroner concluded with an air of triumph that quite squelched the district attorney.

Kennedy was all attention. ‘Have you preserved samples of the blood of Mr Templeton and Miss Wainwright?’ he asked.

‘Certainly. I have them in my office.’

The coroner, who was also a local physician, led us back into his private office.

‘And the cat?’ added Craig.

Doctor Nott produced it in a covered basket.

Quickly Kennedy drew off a little of the blood of the cat and held it up to the light along with the human samples. The difference was apparent.

‘You see,’ he explained, ‘carbon monoxide combines firmly with the blood, destroying the red colouring matter of the red corpuscles. No, Doctor, I’m afraid it wasn’t carbonic oxide that killed the lovers, although it certainly killed the cat.’

Doctor Nott was crestfallen, but still unconvinced. ‘If my whole medical reputation were at stake,’ he repeated, ‘I should still be compelled to swear to asphyxia. I’ve seen it too often, to make a mistake. Carbonic oxide or not, Templeton and Miss Wainwright were asphyxiated.’

It was now Whitney’s chance to air his theory.

‘I have always inclined toward the cyanide-of-potassium theory, either that it was administered
