'I don't know if I could tell you,' said Garrett mendaciously, 'in some public place. But you hadn't finished.'
'Really I had nothing much to add, only that John Eldred, of course, paid no attention whatever to my letters, and has enjoyed the estate ever since, while my daughter and I have had to take to the lodging-house business here, which I must say has not turned out by any means so unpleasant as I feared it might.'
'But about the envelope.'
'To be sure! Why, the puzzle turns on that. Give Mr Garrett the paper out of my desk.'
It was a small slip, with nothing whatever on it but five numerals, not divided or punctuated in any way: 11334.
Mr Garrett pondered, but there was a light in his eye. Suddenly he 'made a face', and then asked, 'Do you suppose that Mr Eldred can have any more clue than you have to the title of the book?'
'I have sometimes thought he must,' said Mrs Simpson, 'and in this way: that my uncle must have made the will not very long before he died (that, I think, he said himself), and got rid of the book immediately afterwards. But all his books were very carefully catalogued: and John has the catalogue: and John was most particular that no books whatever should be sold out of the house. And I'm told that he is always journeying about to booksellers and libraries; so I fancy that he must have found out just which books are missing from my uncle's library of those which are entered in the catalogue, and must be hunting for them.'
'Just so, just so,' said Mr Garrett, and relapsed into thought.

No later than next day he received a letter which, as he told Mrs Simpson with great regret, made it absolutely necessary for him to cut short his stay at Burnstow.
