‘Now the beginning of the troubles arose in a very curious way. Mr Jones had been staying the previous night at a small commercial hotel in Birmingham. It happened that the blotting paper in the blotting book had been put in fresh that day, and the chambermaid, having apparently nothing better to do, amused herself by studying the blotter in the mirror just after Mr Jones had been writing a letter there. A few days later there was a report in the papers of the death of Mrs Jones as the result of eating tinned lobster, and the chambermaid then imparted to her fellow servants the words that she had deciphered on the blotting pad. They were as follows: Entirely dependent on my wife…when she is dead I will…hundreds and thousands…

‘You may remember that there had recently been a case of a wife being poisoned by her husband. It needed very little to fire the imagination of these maids. Mr Jones had planned to do away with his wife and inherit hundreds of thousands of pounds! As it happened one of the maids had relations living in the small market town where the Joneses resided. She wrote to them, and they in return wrote to her. Mr Jones, it seemed, had been very attentive to the local doctor’s daughter, a good-looking young woman of thirty-three. Scandal began to hum. The Home Secretary was petitioned. Numerous anonymous letters poured into Scotland Yard all accusing Mr Jones of having murdered his wife. Now I may say that not for one moment did we think there was anything in it except idle village talk and gossip. Nevertheless, to quiet public opinion an exhumation order was granted. It was one of these cases of popular superstition based on nothing solid whatever, which proved to be so surprisingly justified. As a result of the autopsy sufficient arsenic was found to make it quite clear that the deceased lady had died of arsenical poisoning. It was for Scotland Yard working with the local authorities to prove how that arsenic had been administered, and by whom.’

‘Ah!’ said Joyce. ‘I like this. This is the real stuff.’

‘Suspicion naturally fell on the husband. He benefited by his wife’s death. Not to the extent of the hundreds of thousands romantically imagined by the hotel chambermaid, but to the very solid amount of £8000. He had no money of his own apart from what he earned, and he was a man of somewhat extravagant habits with a partiality for the society of women. We investigated as delicately as possible the rumour of his attachment to the doctor’s daughter; but while it seemed clear that there had been a strong friendship between them at one time, there had been a most abrupt break two months previously, and they did not appear to have seen each other since. The doctor himself, an elderly man of a straightforward and unsuspicious type, was dumbfounded at the result of the autopsy. He had been called in about midnight to find all three people suffering. He had realized immediately the serious condition of Mrs Jones, and had sent back to his dispensary for some opium pills, to allay the pain. In spite of all his efforts, however, she succumbed, but not for a moment did he suspect that anything was amiss. He was convinced that her death was due to a form of botulism. Supper that night had consisted of tinned lobster and salad, trifle and bread and cheese. Unfortunately none of the lobster remained—it had all been eaten and the tin thrown away. He had interrogated the young maid, Gladys Linch. She was terribly upset, very tearful and agitated, and he found it hard to get her to keep to the point, but she declared again and again that the tin had not been distended in any way and that the lobster had appeared to her in a perfectly good condition.
