'How can I tell, Captain!' answered Rob. 'I only know that I'm a heavy sleeper at first, and a light one towards morning; and if Mr Gills had come through the shop near daybreak, though ever so much on tiptoe, I'm pretty sure I should have heard him shut the door at all events.

On mature consideration of this evidence, Captain Cuttle began to think that the Instrument-maker must have vanished of his own accord; to which logical conclusion he was assisted by the letter addressed to himself, which, as being undeniably in the old man's handwriting, would seem, with no great forcing, to bear the construction, that he arranged of his own will to go, and so went. The Captain had next to consider where and why? and as there was no way whatsoever that he saw to the solution of the first difficulty, he confined his meditations to the second.

Remembering the old man's curious manner, and the farewell he had taken of him; unaccountably fervent at the time, but quite intelligible now: a terrible apprehension strengthened on the Captain, that, overpowered by his anxieties and regrets for Walter, he had been driven to commit suicide. Unequal to the wear and tear of daily life, as he had often professed himself to be, and shaken as he no doubt was by the uncertainty and deferred hope he had undergone, it seemed no violently strained misgiving, but only too probable. Free from debt, and with no fear for his personal liberty, or the seizure of his goods, what else but such a state of madness could have hurried him away alone and secretly? As to his carrying some apparel with him, if he had really done so - and they were not even sure of that - he might have done so, the Captain argued, to prevent inquiry, to distract attention from his probable fate, or to ease the very mind that was now revolving all these possibilities. Such, reduced into plain language, and condensed within a small compass, was the final result and substance of Captain Cuttle's deliberations: which took a long time to arrive at this pass, and were, like some more public deliberations, very discursive and disorderly.

Dejected and despondent in the extreme, Captain Cuttle felt it just to release Rob from the arrest in which he had placed him, and to enlarge him, subject to a kind of honourable inspection which he still resolved to exercise; and having hired a man, from Brogley the Broker, to sit in the shop during their absence, the Captain, taking Rob with him, issued forth upon a dismal quest after the mortal remains of Solomon Gills.

Not a station-house, or bone-house, or work-house in the metropolis escaped a visitation from the hard glazed hat. Along the wharves, among the shipping on the bank-side, up the river, down the river, here, there, everywhere, it went gleaming where men were thickest, like the hero's helmet in an epic battle. For a whole week the Captain read of all the found and missing people in all the newspapers and handbills, and went forth on expeditions at all hours of the day to identify Solomon Gills, in poor little ship-boys who had fallen overboard, and in tall foreigners with dark beards who had taken poison - 'to make sure,' Captain Cuttle said, 'that it wam't him.' It is a sure thing that it never was, and that the good Captain had no other satisfaction.

Captain Cuttle at last abandoned these attempts as hopeless, and set himself to consider what was to be done next. After several new perusals of his poor friend's letter, he considered that the maintenance of' a home in the old place for Walter' was the primary duty imposed upon him. Therefore, the Captain's decision was, that he would keep house on the premises of Solomon Gills himself, and would go into the instrument-business, and see what came of it.

But as this step involved the relinquishment of his apartments at Mrs MacStinger's, and he knew that resolute woman would never hear of his deserting them, the Captain took the desperate determination of running away.

'Now, look ye here, my lad,' said the Captain to Rob, when he had matured this notable scheme, 'to-morrow, I shan't be found in this here roadstead till night - not till arter midnight p'rhaps.
