‘Oh, yes, that part of it was all right. He’d even got the letter which was supposed to be written by me. It wasn’t the least bit like my handwriting—but then, of course, he couldn’t be supposed to know that.’

‘Well, let’s state the position clearly,’ said Sir Henry. ‘Correct me if I go wrong. The lady and the maid are decoyed from the house. This young man is decoyed down there by means of a bogus letter—colour being lent to this last by the fact that you actually are performing at Riverbury that week. The young man is doped, and the police are rung up and have their suspicions directed against him. A burglary actually has taken place. I presume the jewels were taken?’

‘Oh, yes.’

‘Were they ever recovered?’

‘No, never. I think, as a matter of fact, Sir Herman tried to hush things up all he knew how. But he couldn’t manage it, and I rather fancy his wife started divorce proceedings in consequence. Still, I don’t really know about that.’

‘What happened to Mr Leslie Faulkener?’

‘He was released in the end. The police said they hadn’t really got enough against him. Don’t you think the whole thing was rather odd?’

‘Distinctly odd. The first question is whose story to believe? In telling it, Miss Helier, I noticed that you incline towards believing Mr Faulkener. Have you any reason for doing so beyond your own instinct in the matter?’

‘No-no,’ said Jane unwillingly. ‘I suppose I haven’t. But he was so very nice, and so apologetic for having mistaken anyone else for me, that I feel sure he must have been telling the truth.’

‘I see,’ said Sir Henry smiling. ‘But you must admit that he could have invented the story quite easily. He could write the letter purporting to be from you himself. He could also dope himself after successfully committing the burglary. But I confess I don’t see where the point of all that would be. Easier to enter the house, help himself, and disappear quietly—unless just possibly he was observed by someone in the neighbourhood and knew himself to have been observed. Then he might hastily concoct this plan for diverting suspicion from himself and accounting for his presence in the neighbourhood.’

‘Was he well off?’ asked Miss Marple.

‘I don’t think so,’ said Jane. ‘No, I believe he was rather hard up.’

‘The whole thing seems curious,’ said Dr Lloyd. ‘I must confess that if we accept the young man’s story as true, it seems to make the case very much more difficult. Why should the unknown woman who pretended to be Miss Helier drag this unknown man into the affair? Why should she stage such an elaborate comedy?’

‘Tell me, Jane,’ said Mrs Bantry. ‘Did young Faulkener ever come face to face with Mary Kerr at any stage of the proceedings?’

‘I don’t quite know,’ said Jane slowly, as she puzzled her brows in remembrance.

‘Because if he didn’t the case is solved!’ said Mrs Bantry. ‘I’m sure I’m right. What is easier than to pretend you’re called up to town? You telephone to your maid from Paddington or whatever station you arrive at, and as she comes up to town, you go down again. The young man calls by appointment, he’s doped, you set the stage for the burglary, overdoing it as much as possible. You telephone the police, give a description of your scapegoat, and off you go to town again. Then you arrive home by a later train and do the surprised innocent.’
