“‘Office-boy,’ I ses.  ’He’d better not see you at all.  S’pose you go off for a bit and come back when I whistle?’

“Afore she could answer the boy came out of the office, ready to go ’ome.  He gave a little bit of a start when ’e saw me talking to a lady, and then ‘e nips down sudden, about a couple o’ yards away, and begins to do ’is bootlace up.  It took ’im some time, because he ’ad to undo it fust, but ’e finished it at last, and arter a quick look at Mrs. Pratt, and one at me that I could ha’ smacked his ’ed for, ’e went off whistling and showing ’is little cuffs.

“I stepped out into the road and watched ‘im out o’ sight.  Then I told Mrs. Pratt to pick up ’er bag and foller me.

“As it ’appened there was a big pile of empties in the corner of the ware’ouse wall, just opposite the Eastern Monarch’s berth.  It might ha’ been made for the job, and, arter I ’ad tucked her away behind and given ’er a box to sit on, I picked up my broom and began to make up for lost time.

“She sat there as quiet as a cat watching a mouse’ole, and I was going on with my work, stopping every now and then to look and see whether the Monarch was in sight, when I ’appened to turn round and see the office-boy standing on the edge of the wharf with his back to the empties, looking down at the water.  I nearly dropped my broom.

“‘’Ullo!’ I ses, going up to ’im.  ’I thought you ’ad gorn ‘ome.’

“‘I was going,’ he ses, with a nasty oily little smile, ’and then it struck me all of a sudden ’ow lonely it was for you all alone ’ere, and I come back to keep you company.’

“He winked at something acrost the river as ’e spoke, and I stood there thinking my ’ardest wot was the best thing to be done.  I couldn’t get Mrs. Pratt away while ’e was there; besides which I felt quite sartain she wouldn’t go.  The only ’ope I ’ad was that he’d get tired of spying on me and go away before he found out she was ’iding on the wharf.

“I walked off in a unconcerned way—­not too far—­and, with one eye on ’im and the other on where Mrs. Pratt was ’iding, went on with my work.  There’s nothing like ’ard work when a man is worried, and I was a’most forgetting my troubles, when I looked up and saw the Monarch coming up the river.

“She turned to come into ’er berth, with the skipper shouting away on the bridge and making as much fuss as if ’e was berthing a liner.  I helped to make ’er fast, and the skipper, arter ’e had ’ad a good look round to see wot ’e could find fault with, went below to clean ’imself.

“He was up agin in about ten minutes, with a clean collar and a clean face, and a blue neck-tie that looked as though it ’ad got yeller measles.  Good temper ’e was in, too, and arter pulling the office-boy’s ear, gentle, as ’e was passing, he stopped for a moment to ’ave a word with ’im.

“‘Bit late, ain’t you?’ he ses.

“‘I’ve been keeping a eye on the watchman,’ ses the boy.  ’He works better when ’e knows there’s somebody watching ‘im.’
