When we arrived on the platform the first person we saw was Inspector Crome.

He answered Poirot’s look of inquiry.

‘No news as yet. All men available are on the lookout. All persons whose name begins with C are being warned by phone when possible. There’s just a chance. Where’s the letter?’

Poirot gave it to him.

He examined it, swearing softly under his breath.

‘Of all the damned luck. The stars in their courses fight for the fellow.’

‘You don’t think,’ I suggested, ‘that it was done on purpose?’

Crome shook his head.

‘No. He’s got his rules—crazy rules—and abides by them. Fair warning. He makes a point of that. That’s where his boastfulness comes in. I wonder now—I’d almost bet the chap drinks White Horse whisky.’

‘Ah, c’est ingénieux, c¸a!’ said Poirot, driven to admiration in spite of himself. ‘He prints the letter and the bottle is in front of him.’

‘That’s the way of it,’ said Crome. ‘We’ve all of us done much the same thing one time or another, unconsciously copied something that’s just under the eye. He started off White and went on horse instead of haven…’

The inspector, we found, was also travelling by the train.

‘Even if by some unbelievable luck nothing happened, Churston is the place to be. Our murderer is there, or has been there today. One of my men is on the phone here up to the last minute in case anything comes through.’

Just as the train was leaving the station we saw a man running down the platform. He reached the inspector’s window and called up something.

As the train drew out of the station Poirot and I hurried along the corridor and tapped on the door of the inspector’s sleeper.

‘You have news—yes?’ demanded Poirot.

Crome said quietly:

‘It’s about as bad as it can be. Sir Carmichael Clarke has been found with his head bashed in.’

Sir Carmichael Clarke, although his name was not very well known to the general public, was a man of some eminence. He had been in his time a very well-known throat specialist. Retiring from his profession very comfortably off, he had been able to indulge what had been one of the chief passions of his life—a collection of Chinese pottery and porcelain. A few years later, inheriting a considerable fortune from an elderly uncle, he had been able to indulge his passion to the full, and he was now the possessor of one of the best-known collections of Chinese art. He was married but had no children and lived in a house he had built for himself near the Devon coast, only coming to London on rare occasions such as when some important sale was on.

It did not require much reflection to realize that his death, following that of the young and pretty Betty Barnard, would provide the best newspaper sensation for years. The fact that it was August and that the papers were hard up for subject matter would make matters worse.
