However, Mr Karswell was an astute man.
This much is in the way of prologue. On an evening rather later in the same week, Mr Edward Dunning was returning from the British Museum, where he had been engaged in research, to the comfortable house in a suburb where he lived alone, tended by two excellent women who had been long with him. There is nothing to be added by way of description of him to what we have heard already. Let us follow him as he takes his sober course homewards.
A train took him to within a mile or two of his house, and an electric tram a stage farther. The line ended at a point some three hundred yards from his front door. He had had enough of reading when he got into the car, and indeed the light was not such as to allow him to do more than study the advertisements on the panes of glass that faced him as he sat. As was not unnatural, the advertisements in this particular line of cars were objects of his frequent contemplation, and, with the possible exception of the brilliant and convincing dialogue between Mr Lamplough and an eminent KC on the subject of Pyretic Saline, none of them afforded much scope to his imagination. I am wrong: there was one at the corner of the car farthest from him which did not seem familiar. It was in blue letters on a yellow ground, and all that he could read of it was a name--John Harrington--and something like a date. It could be of no interest to him to know more; but for all that, as the car emptied, he was just curious enough to move along the seat until he could read it well. He felt to a slight extent repaid for his trouble; the advertisement was not of the usual type. It ran thus: 'In memory of John Harrington, FSA, of The Laurels, Ashbrooke. Died Sept. 18th, 1889. Three months were allowed.'The car stopped. Mr Dunning, still contemplating the blue letters on the yellow ground, had to be stimulated to rise by a word from the conductor. 'I beg your pardon,' he said, 'I was looking at that advertisement; it's a very odd one, isn't it?' The conductor read it slowly. 'Well, my word,' he said, 'I never see that one before. Well, that is a cure, ain't it? Someone bin up to their jokes 'ere, I should think.' He got out a duster and applied it, not without saliva, to the pane and then to the outside. 'No,' he said, returning, 'that ain't no transfer; seems to me as if it was reg'lar in the glass, what I mean in the substance, as you may say. Don't you think so, sir?' Mr Dunning examined it and rubbed it with his glove, and agreed. 'Who looks after these advertisements, and gives leave for them to be put up? I wish you would inquire. I will just take a note of the words.' At this moment there came a call from the driver: 'Look alive, George, time's up.' 'All right, all right; there's somethink else what's up at this end. You come and look at this 'ere glass.' 'What's gorn with the glass?' said the driver, approaching. 'Well, and oo's 'Arrington? What's it all about?' 'I was just asking who was responsible for putting the advertisements up in your cars, and saying it would be as well to make some inquiry about this one.' 'Well, sir, that's all done at the Company's orfice, that work is: it's our Mr Timms, I believe, looks into that. When we put up tonight I'll leave word, and per'aps I'll be able to tell you tomorrer if you 'appen to be coming this way.'
