gummed paper until it exactly fitted the cavity. The ends of this paper had then been masked with plasticine, coloured so as to match the mortar exactly. Upon replacement of the brick no visible sign remained of the wall having been tampered with.
Jimmy examined the paper in which the brick had been wrapped. He saw at once that it consisted of sheets of some periodical. On removing one or two layers, he found a sheet upon which the name of the periodical appeared. It was the British Medical Journal of the preceding May 22.
He put the brick back very carefully in its place. Then he picked up the army greatcoat and made his way back with it to the police station.
Sergeant Cload’s face stiffened as he caught sight of his burden. ‘Wherever did you find that, sir, if I may ask?’ he exclaimed.
‘In the very spot where Alfie says he spent last Friday night,’ Jimmy replied. ‘Bring him along here again for a minute, will you?’
Alfie reappeared and Jimmy held the coat up before his eyes. ‘Did you ever see this before, Alfie?’ he asked.
Alfie’s eyes opened wide in amazement. ‘Why glory hallelujah! If it isn’t my old coat come back to find me,’ he exclaimed. Then he frowned suspiciously. ‘You must be the cove that took it off me,’ he said with an air of finality.
‘Wrong this time, Alfie,’ Jimmy replied. ‘All right, sergeant, take him away.’
By the time that Cload returned, Jimmy was busy drawing a plan in his notebook. He looked up and grinned cheerfully at the sergeant. ‘Jolly case, this,’ he said. ‘It’s absolutely brimful of contradictions. To begin with, how did Alfie’s coat find its way to the corner where its original possessor spent Friday night?’
Cload shook his head. ‘You can’t take any heed of what Alfie says when he’s like this, sir,’ he replied. ‘I wouldn’t go so far as to say that he was deliberately lying when he told us that story just now. He may honestly have believed that those things had really happened, whereas he had only imagined or dreamt them.’
‘Wait a minute,’ said Jimmy, taking the paper containing the cigarette ends from his pocket. ‘I found these lying on the grass under Alfie’s coat just now. Alfie can’t have enjoyed them very much, for in nearly every case he’s left an inch of stump. And if you look closely at them, sergeant, you can see the name of the brand printed on them. Black’s Russian Blend.’
‘Yes, I can see that plain enough, sir,’ Cload replied. ‘But I don’t know that I’ve ever heard of them before.’
‘That’s very likely, for they aren’t sold everywhere. You can only get them at one of Black’s shops in London. It seems to me that those cigarette ends to some extent confirm Alfie’s story of the cove he met.’
Cload looked a trifle dubious. ‘When Alfie’s in these moods, he’ll ask anybody he meets for fags. And it doesn’t follow that whoever gave him these asked for his coat in exchange.’
‘It doesn’t follow, certainly. Your theory, I take it, is that Alfie, following his usual habit, accosted some worthy citizen of Adderminster and was given the cigarettes of which these are the ends.’
‘That’s about it, sir. I don’t somehow believe in the man with the flashlamp who bought Alfie’s coat. Whoever could want such a filthy old thing as that?’
‘Ah, that’s just it! But do you know anybody in Adderminster who smokes Black’s Russian Blend?’
‘I can’t say that I do, sir, but that doesn’t count for much. There are plenty of people in Adderminster who go up to London three and four times a week. There’s nothing to prevent any of them from buying these cigarettes at one of the shops you speak of, sir.’
‘I wonder if Dr Thornborough smokes them?’
Cload shook his head. ‘The doctor only smokes a pipe, sir. I’ve heard him say more than once that cigarettes always make him cough.’
Jimmy glanced at the clock. ‘It’s a quarter to one now,’ he said. ‘If I walk up to Epidaurus, I ought to catch the doctor as he comes home to lunch.’
When Jimmy reached the house, Lucy informed him that the doctor had already returned, and showed him into the consulting-room. Here, a minute later, Dr Thornborough joined him. He looked very careworn, and it was easy to tell that the events of the last twenty-four hours had played havoc with his nerves.
‘Well, inspector?’ he demanded curtly. ‘What’s your business?’
‘My business is concerned with Alfie Prince, doctor,’ replied Jimmy quietly.
Dr Thornborough had clearly expected a very different answer. ‘Alfie Prince!’ he said, wearily passing his hand across his forehead. ‘I’d forgotten all about him. You must excuse me, but this terrible affair has shaken me up pretty badly. What do you want me to do about Alfie Prince?’
‘Nothing, just now, doctor. Alfie’s out of mischief for the moment in one of the cells at the police station. You saw him yesterday on your way home to luncheon, didn’t you?’
‘Not to speak to. He merely happened to cross the road in front of me.’
‘How far away from you was he when you saw him?’
‘Oh, a couple of hundred yards, I dare say. Certainly not less.’
‘Did you notice him particularly?’
‘I can’t say that I did. Seeing that it was Alfie, I didn’t take any further notice of him,’
‘Were you surprised to find him wandering about up here?’
Dr Thornborough smiled a trifle wanly. ‘Nobody in Adderminster is ever very much surprised at what Alfie does. Besides, he’s a sufferer from claustrophobia, and I happen to know that sometimes he spends his nights in the field adjoining this house.’
‘Do you happen to know whether he spent last Friday night there?’
‘I don’t, for I never look to see whether he’s there or not. Officially I know nothing about it, for I suppose that technically he’s trespassing. But he isn’t doing any harm, and from the medical point of view it’s better for him to sleep out than in.’
‘He was coming out of that field when you saw him, wasn’t he?’
‘Yes. He crossed the road into the orchard opposite, and I didn’t see any more of him after that.’
‘You’re perfectly certain that the man you saw was Alfie?’
‘Oh, anyone who knew him would recognise him a mile away. He always wears a filthy old army greatcoat, so ragged that it’s literally dropping off him. And as soon as I caught sight of that coat I knew it must be Alfie.’
‘Where were you coming from when you saw him, doctor?’
‘I’d been to Mark Farm. Mrs Hawksworth, the farmer’s wife is one of my patients. I’d been to Weaver’s Bridge and I drove up to the farm from that direction. I was there about a quarter of an hour, I dare say, and then I came home through the gate at the end of the road.’
‘Did
