Young Blood by E.W. Hornung

Harry had hoped that his companion would go his own way when they got to London; but it was "his funeral," as Mr. Lowndes kept saying, and he seemed determined to conduct it to the end. Euston was crowded, where Lowndes behaved like a man in his element, dealing abuse and largesse with equal energy and freedom, and getting Harry and all his boxes off in the first cab which left the station. But he himself was at Harry's side; and there he sat until the cab stopped, half-an-hour later, beneath a many-windowed red-brick pile thrown up in the angle of two back streets.

A porter in uniform ran up to help with the luggage, and, as Harry jumped out, a voice with a glad sob in it hailed him from a first-floor window. He waved his hat, and, with a pang, saw a white head vanishing: it had not been white when he went away. Next moment he was flying up the stone stairs three at a time; and on the first landing, at an open door, there was the sweet face, all aged and lined and lighted with sorrow and shame and love; there were the softest arms in all the world, spread wide to catch and clasp him to the warmest heart.
