As day by day went by, in patient monotony, Roger became daily more aware of this ghostly attendant.  He was not always alone, for he had friends who loved him in spite of the Shadow, and grew used to its appearing;—­but he liked to be by himself; for, out of constant companionship and daily use, this Shadow made for itself a strange affinity with him, and following his daily rambles over the sharp hills, tracing to their source the noisy brooks, or setting snares for the wild creatures whose innocent timid eyes peered at their little enemy curiously from nook and crevice, he grew to have a moody pleasure in the knowledge that nothing else disturbed his path or shared his amusements.

But a time came when he must mix more with the outer world; for he was sent away from home to school, and there, amid a host of strange faces, he singled out the only one that had a thought of his past life and home in it, as his special companion,—­the same quiet boy who had unconsciously feared the Shadow in their earlier school-days.

So good and gentle was he, that he did not feel the cloud of Roger’s hateful Double as every one else did; and he even won the boy himself to except him only from a certain suspicion that had lately sprung from, his own consciousness of his burden,—­a suspicion gradually growing into a belief that all the world had such a Shadow as his own.

Now this was not a strange result of so painful a reality.  Seeing, as Roger Pierce did, in every action of others toward himself the dark atmosphere of the Shadow that was peculiarly his own, he watched also their mutual actions, and, throwing from his own obscurity a shade over all human deeds, he became possessed of the monomania, a practical belief that every mortal man, except it might be Jimmy Doane, was followed and overlooked by this terrible Second Shadow.

In proportion as the gloom of this black Presence seemed to be lightened over any one was his esteem for him; but by daily looking so steadily and with such a will to see only darkness in the hearts of men, he discovered traces of the Shadow even in Jimmy Doane,—­and the darkness shut down, like night at sea, over all the world then.

Now Roger was miserable enough, knowing well that he could escape, if he would; for there had come with his increasing sense of his tyrant, a knowledge that every time he thought of the Shadow it darkened more deeply than ever, and that in forgetting it lay his only hope of escape from its power.  But withal there was a morbid pleasure, the reflex influence of habit and indolence, that mingled curiously with his longing desire to forget his Double, but rendered it impossible to do so without a greater effort than he cared to make, or some help from another hand; and soon that help seemed to come.

When Roger left his home for school, he left in the quaint oak cradle a little baby-sister, too young to have a place in his thought as a definite existence; but after an absence of two years he came back to find in her a new phase of life, into which the Shadow could not yet enter.
