His errant memory had returned to the poetry prize once more.

'Oh,' said the Colonel, 'why is that?'

Pringle explained the peculiar disadvantages that attended membership of the Upper Fifth during the summer term.

'I don't think a man ought to be allowed to spend his money in these special prizes,' he concluded; 'at any rate they ought to be Sixth Form affairs. It's hard enough having to do the ordinary work and keep up your cricket at the same time.'

'They are compulsory then?'

'Yes. Swindle, I call it. The chap who shares my study at Beckford is in the Upper Fifth, and his hair's turning white under the strain. The worst of it is, too, that I've promised to help him, and I never seem to have any time to give to the thing. I could turn out a great poem if I had an hour or two to spare now and then.'

'What's the subject?'

'Death of Dido this year. They are always jolly keen on deaths. Last year it was Cato, and the year before Julius Caesar. They seem to have very morbid minds. I think they might try something cheerful for a change.'

'Dido,' said the Colonel dreamily. 'Death of Dido. Where have I heard either a story or a poem or a riddle or something in some way connected with the death of Dido? It was years ago, but I distinctly remember having heard somebody mention the occurrence. Oh, well, it will come back presently, I dare say.'

It did come back presently. The story was this. A friend of Colonel Ashby's—the one-time colonel of his regiment, to be exact—was an earnest student of everything in the literature of the country that dealt with Sport. This gentleman happened to read in a publisher's list one day that a limited edition of The Dark Horse, by a Mr Arthur James, was on sale, and might be purchased from the publisher by all who were willing to spend half a guinea to that end.
