He did so after giving me a look as if he suspected I meant to squeeze him overboard through the aperture.

‘Out now with that pot and brush.’

He tossed them into the sea. I turned down the lamp till only the feeblest glimmer of flame remained, and then sure enough there stole out upon the bulkhead in a feeble, green, glittering scrawl that seemed to wink upon the sight with its coming and going the words ‘Return to Ba—.’

‘Rub that off at once,’ said I, ‘and be quick about it too. If Sir Wilfrid arrives I shall have to explain; and he’s a man to shoot you for such an act as this.’

He pulled a pocket handkerchief out of his coat-tail and fell to rubbing the bulkhead with a terrified hand, backing to see if the letters were gone, then applying himself afresh, breathing hard meanwhile and manifesting much fear, for no doubt he believed that my hint that Wilfrid would shoot him was very well founded, seeing that he had a half-crazy man to deal with in his master. He rubbed till nothing was left of the letters. I turned up the lamp and ordered him out of the cabin. He was about to address me.

‘Not a word,’ I cried, subduing my voice, for though my temper was such that I could scarce keep my hands off him, yet I was exceedingly anxious too that Wilfrid should not overhear me nor come to his berth and find me in it with his valet. ‘Get away forward now to your own cabin.’

‘For God’s sake, Mr. Monson, don’t tell Sir Wilfrid, sir,’ he exclaimed, in a hoarse, broken tone.

‘Away with you! I promise nothing. This is a matter to think over. I shall require to talk with you in the morning.’

I held open the cabin door and he passed out in a sideways fashion as if he feared I should hit him, and then travelled swiftly forwards with such a twinkling of the white socks bulging over his pumps as made me believe he ran. My cousin was still on deck. Miss Jennings gazed at me earnestly; I looked to see if the coast was clear, and exclaimed: ‘It proved as I had supposed. I have interpreted the warning Wilfrid has received.’

She gazed at me in silence.
