“Beaton, when will you cease to play these senseless and annoying tricks? Your folly caused six hundred boys, to say nothing of the masters, to lose twenty precious minutes. If I punished you as you deserve, you ought to stay in for twenty minutes each day for six hundred days....”

Tod gasped.

“But I won’t do that. Instead, you must do a thousand lines, to be given up by the end of this week. I shall not cane you, as I have no doubt you would infinitely prefer it.”

A good many boys assisted to write those lines, and the impost was given up at its appointed time.

Hockey leagues were on and Peter was playing in his house team. On the morning of the last practice before an important match, he acknowledged so barely bowing an acquaintance with certain French idioms beloved of the French master—for was he not their author?—that Peter was told to stay in after morning school and learn them.

Peter did nothing of the kind; on the contrary, he went out at the usual hour and played hockey with his accustomed vigor, with the result that the French master sent for him that afternoon to know why he had not done as he was told.

Peter pleaded “a very important engagement,” and, on being pressed to disclose the nature of that same, as usual answered quite truthfully. The French master, not unnaturally exasperated, forthwith reported him to the Head of the Modern, with the result that Peter was hauled up and bidden to stay in on the next half-holiday; the very half-holiday on which his house was to play its bitterest rival.

During the remainder of that term he got into several rows with his form-master, and Tod was equally unlucky, so that by the time the Easter holidays arrived both boys were quite ready for them and left school vowing vengeance on their persecutors.

Their parents were in India, so they went to spend the holidays with a jolly young bachelor uncle, who was an ardent fisherman and carried both the boys off with him for three weeks’ peel-fishing in a remote village in North Wales. He was also of a literary turn, that uncle, and took with him a box of books to enliven their evenings: lots of Kipling and Stevenson, and amongst the latter the “Life and Letters.” He read aloud the “Thomas Libby” incident, where Stevenson and certain kindred spirits roused a whole neighborhood to excitement by constant inquiries as to the whereabouts of one “Thomas Libby,” who existed only in his creator’s vivid imagination. That of the twins was immediately fired by an ambition to go and do likewise.

The incident, or rather series of incidents, to which the non-appearance of Mr. Libby led up, enchanted them. They chuckled over the mysterious Thomas for a whole day, but it was not till evening, at bedtime, that Tod whispered to Peter how, like “Sentimental Tommy,” he had “found a way.”
