It was a hot, stifling summer day, and perhaps Whitechapel never looked more grimy, more squalid, more sorrowful, perforce from its pathetic contrast to the summer beauty of the skies.

The pavement was so hot that the heat seemed to rise up, flouting itself in your very face.

In one particular alley, known as Mulliner's Rents, the heat seemed almost tropical. Possibly the dense overcrowding of this quarter with human life enhanced the burning sensation of the thick air breathed out and breathed in again, unrefreshed, by multitudes of lungs. Here, there, and everywhere human beings stood about idly. Groups of untidy women, in twos and threes, gossiped; lazy men lolled against the houses, smoking in sullen silence; and for every grown-up person there were fully a dozen of squalid children playing, shouting, staring, and squabbling with a vigour no heat could abate.

There was little traffic, so to say, in Mulliner's Rents; it was quite select in that one single respect. Nothing on wheels penetrated the unlovely quarter save a coster's barrow of fruit; unwholesome little yellow pears and cruelly green apples of the lowest type of apple-kind being the wares of the moment. It was truly a sad and sorrowful haunt, this of the man-made town; and so it seemed to the two travellers fresh from the God-made country—from the wholesome breezes of the caller salt air of Northbourne—when they plunged into its midst.

'Courage, captain!' said Philip Price, when he noticed the blanching of the elder man's brown face and the unutterable loathing of horror that spoke out of every feature. 'We've got to put our shoulder to the wheel, and leave no stone unturned to find Alick, and carry him out of this pestilent hole.'

Philip Price, before his health broke down, had been for a few months doing duty as curate in a still more squalid colony of human nests than even this. When the sailor flinched, and hung back, Philip strode forward, determined to conquer, unheeding the battery of stares turned upon himself and his companion by the inhabitants, and the free-and-easy comments, of which they were by no means chary.

Already the captain and Philip had that day spent many fruitless hours in the search, when they hit on a fresh clue and an address in Mulliner's Rents. But here, even, difficulties bristled, and the tide of hopelessness was setting in upon both men when a wretched old crone was dragged out of a public-house to confront them, with dazed eyes and with a hateful odour of gin oozing from her whole person.

'Yes—well, yes,' she grudgingly admitted, in answer to the eager questions of the searchers; 'I does know a boy down with fever. What o' that? I ain't done no harm to him! He's 'ad the best I could offer; and five shillin's don't go far when there's sickness,' she ended, with a whimper, for she was maudlin with drink.

'Take us to that boy at once!' commanded Philip Price; for the captain's agitation unmanned him for the moment.

The wretched woman, awed by Philip's tone, complied. Perhaps, also, she obeyed, half in fear of the policeman, who had stepped up to join the gentlemen, and half in hope of getting more silver to spend on more drink.

Before half an hour was over Alick Carnegy was found. It was a terrible shock to the captain to recognise his boy in the squalid, dirty, delirious sufferer tossing wearily on a heap of sacks, on the grimy floor of an attic at the top of an evil-smelling, dilapidated house, to which the crone stumblingly conducted them.

'Merciful powers!' he groaned in dismayed horror.

'Hush!' enjoined Philip. 'Be as calm as you can. I believe the poor little chap is off his head; but, if there's a gleam of consciousness, it would send him over the precipice again to witness your agitation.'

There was small fear of the captain doing any further mischief; he was stunned into helplessness, and stood mute, trying to force himself to believe that the huddled heap of squalid misery was his very own son—smart, manly-looking Alick Carnegy. Though the captain was thus helpless, Philip Price seemed to know exactly what to do, and how to do it.

Getting the address of a doctor, he rushed off, in the first place, to fetch him. Then a bedstead and clean bedding were hired in. In an hour or two more the grimy room was swept and tidied as far as po............
