At first the Captain was too much confounded and distressed to think of anything but the letter itself; and even when his thoughts began to glance upon the various attendant facts, they might, perhaps, as well have occupied themselves with their former theme, for any light they reflected on them. In this state of mind, Captain Cuttle having the Grinder before the court, and no one else, found it a great relief to decide, generally, that he was an object of suspicion: which the Captain so clearly expressed in his visage, that Rob remonstrated.

'Oh, don't, Captain!' cried the Grinder. 'I wonder how you can! what have I done to be looked at, like that?'

'My lad,' said Captain Cuttle, 'don't you sing out afore you're hurt. And don't you commit yourself, whatever you do.'

'I haven't been and committed nothing, Captain!' answered Rob.

'Keep her free, then,' said the Captain, impressively, 'and ride easy.

With a deep sense of the responsibility imposed upon him' and the necessity of thoroughly fathoming this mysterious affair as became a man in his relations with the parties, Captain Cuttle resolved to go down and examine the premises, and to keep the Grinder with him. Considering that youth as under arrest at present, the Captain was in some doubt whether it might not be expedient to handcuff him, or tie his ankles together, or attach a weight to his legs; but not being clear as to the legality of such formalities, the Captain decided merely to hold him by the shoulder all the way, and knock him down if he made any objection.

However, he made none, and consequently got to the Instrument-maker's house without being placed under any more stringent restraint. As the shutters were not yet taken down, the Captain's first care was to have the shop opened; and when the daylight was freely admitted, he proceeded, with its aid, to further investigation.

The Captain's first care was to establish himself in a chair in the shop, as President of the solemn tribunal that was sitting within him; and to require Rob to lie down in his bed under the counter, show exactly where he discovered the keys and packet when he awoke, how he found the door when he went to try it, how he started off to Brig Place - cautiously preventing the latter imitation from being carried farther than the threshold - and so on to the end of the chapter. When all this had been done several times, the Captain shook his head and seemed to think the matter had a bad look.

Next, the Captain, with some indistinct idea of finding a body, instituted a strict search over the whole house; groping in the cellars with a lighted candle, thrusting his hook behind doors, bringing his head into violent contact with beams, and covering himself with cobwebs. Mounting up to the old man's bed-room, they found that he had not been in bed on the previous night, but had merely lain down on the coverlet, as was evident from the impression yet remaining there.

'And I think, Captain,' said Rob, looking round the room, 'that when Mr Gills was going in and out so often, these last few days, he was taking little things away, piecemeal, not to attract attention.'

'Ay!' said the Captain, mysteriously. 'Why so, my lad?'

'Why,' returned Rob, looking about, 'I don't see his shaving tackle. Nor his brushes, Captain. Nor no shirts. Nor yet his shoes.'

As each of these articles was mentioned, Captain Cuttle took particular notice of the corresponding department of the Grinder, lest he should appear to have been in recent use, or should prove to be in present possession thereof. But Rob had no occasion to shave, was not brushed, and wore the clothes he had on for a long time past, beyond all possibility of a mistake.

'And what should you say,' said the Captain - 'not committing yourself - about his time of sheering off? Hey?'

'Why, I think, Captain,' returned Rob, 'that he must have gone pretty soon after I began to snore.'

'What o'clock was that?' said the Captain, prepared to be very particular about the exact time.
