'So was Mr. Feist's, as it turned out. I found enough to convince me that he is the writer of all those articles about Van Torp, including the ones in which you are mentioned. The odd thing about it is that I found a very friendly invitation from Van Torp himself, begging Mr. Feist to go down to Derbyshire and stop a week with him.'
Margaret leaned back in her chair and looked at her guest in quiet surprise.
'What does that mean?' she asked. 'Is it possible that Mr. Van Torp has got up this campaign against himself in order to play some trick on the Stock Exchange?'
'That's not the way such things are usually managed,' he answered. 'A hundred years ago a publisher paid a critic to attack a book in order to make it succeed, but in finance abuse doesn't contribute to our success, which is always a question of credit. All these scurrilous articles have set the public very much against Van Torp, from Paris to San Francisco, and this man Feist is responsible for them. He is either insane, or he has some grudge against Van Torp, or else he has been somebody's instrument, which looks the most probable.'
'What did you find amongst his papers?' Margaret asked, quite forgetting her vicarious scruples about reading a sick man's letters.
'A complete set of the articles that have appeared, all neatly filed, and a great many notes for more, besides a lot of stuff written in cypher. It must be a diary, for the days are written out in full and give the days of the week.'
'I wonder whether there was anything about the explosion,' said Margaret thoughtfully. 'He said he was there, did he not?'
'It was a Wednesday, I'm sure, and it was after the middle of March. My maid can tell us, for she writes down the date and the opera in a little book each time I sing. It's sometimes very convenient. But it's too late now, of course, and, besides, you could not have read the cypher.'
'That's an easy matter,' Logotheti answered. 'All cyphers can be read by experts, if there is no hurry, except the mechanical ones that are written through holes in a square plate which you turn round till the sheet is full. Hardly any one uses those now, because when the square is raised the letters don't form words, and the cable companies will only transmit real words in some known language, or groups of figures. The diary is written hastily, too, not at all as if it were copied from the sheet on which the perforated plate would have had to be used, and besides, the plate itself would be amongst his things, for he could not read his own notes without it.'
