‘No, it was half a crown!’ Japp had recovered his temper, and grinned. ‘Pretty extravagant, these rich Americans!’
‘And in consequence the boy did not forget her?’
‘Not he. Half-crowns don’t come his way every day. She hailed him and bought two magazines. One had a picture of a girl in blue on the cover. “That’ll match me,” she said. Oh, he remembered her perfectly. Well, that was enough for me. By the doctor’s evidence, the crime must have been committed before Taunton. I guessed they’d throw the knife away at once, and I walked down the line looking for it; and sure enough, there it was. I made inquiries at Taunton about our man, but of course it’s a big station, and it wasn’t likely they’d notice him. He probably got back to London by a later train.’
Poirot nodded. ‘Very likely.’
‘But I found another bit of news when I got back. They’re passing the jewels, all right! That large emerald was pawned last night—by one of the regular lot. Who do you think it was?’
‘I don’t know—except that he was a short man.’
Japp stared. ‘Well, you’re right there. He’s short enough. It was Red Narky.’
‘Who is Red Narky?’ I asked.
‘A particularly sharp jewel-thief, sir. And not one to stick at murder. Usually works with a woman—Gracie Kidd; but she doesn’t seem to be in it this time—unless she’s got off to Holland with the rest of the swag.’
‘You’ve arrested Narky?’
‘Sure thing. But mind you, it’s the other man we want—the man who went down with Mrs Carrington in the train. He was the one who planned the job, right enough. But Narky won’t squeal on a pal.’
I noticed Poirot’s eyes had become very green.
‘I think,’ he said gently, ‘that I can find Narky’s pal for you, all right.’
‘One of your little ideas, eh?’ Japp eyed Poirot sharply. ‘Wonderful how you manage to deliver the goods sometimes, at your age and all. Devil’s own luck, of course.’
‘Perhaps, perhaps,’ murmured my friend. ‘Hastings, my hat. And the brush. So! My galoshes, if it still rains! We must not undo the good work of that tisane. Au revoir, Japp!’
‘Good luck to you, Poirot.’
Poirot hailed the first taxi we met, and directed the driver to Park Lane.
When we drew up before Halliday’s house, he skipped out nimbly, paid the driver and rang the bell. To the footman who opened the door he made a request in a low voice, and we were immediately taken upstairs. We went up to the top of the house, and were shown into a small neat bedroom.
Poirot’s eyes roved round the room and fastened themselves on a small black trunk. He knelt in front of it, scrutinized the labels on it, and took a small twist of wire from his pocket.
‘Ask Mr Halliday if he will be so kind as to mount to me here,’ he said over his shoulder to the footman.
The man departed, and Poirot gently coaxed the lock of the trunk with a practised hand. In a few minutes the lock gave, and he raised the lid of the trunk. Swiftly he began rummaging among the clothes it contained, flinging them out on the floor.
There was a heavy step on the stairs, and Halliday entered the room.
‘What in hell are you doing here?’ he demanded, staring.
‘I was looking, monsieur, for this.’ Poirot withdrew from the trunk a coat and skirt of bright blue frieze, and a small toque of white fox fur.
‘What are you doing with my trunk?’ I turned to see that the maid, Jane Mason, had entered the room.
‘If you will just shut the door, Hastings. Thank you. Yes, and stand with your back against it. Now, Mr Halliday, let me introduce you to Gracie Kidd, otherwise Jane Mason, who will shortly rejoin her accomplice, Red Narky, under the kind escort of Inspector Japp.’

Poirot waved a deprecating hand. ‘It was of the most simple!’ He helped himself to more caviar.
‘It was the maid’s insistence on the clothes that her mistress was wearing that first struck me. Why was she so anxious that our attention should be directed to them? I reflected that we had only the maid’s word for the mysterious man in the carriage at Bristol. As far as the doctor’s evidence went, Mrs Carrington might easily have been murdered before reaching Bristol. But if so, then the maid must be an accomplice. And if she were an accomplice, she would not wish this point to rest on her evidence alone. The clothes Mrs Carrington was wearing were of a striking nature. A maid usually has a good deal of choice as to what her mistress shall wear. Now if, after Bristol, anyone saw a lady in a bright blue coat and skirt, and a fur toque, he will be quite ready to swear he had seen Mrs Carrington.
