‘But why, Mr. Holmes, why?’

’Ah, that’s the question, of course.  But I commend the idea to your mind.  You might possibly find that there was something in it.  You won’t stop for dinner?  Well, goodbye, and let us know how you get on.’

Dinner was over, and the table cleared before Holmes alluded to the matter again.  He had lit his pipe and held his slippered feet to the cheerful blaze of the fire.  Suddenly he looked at his watch.

‘I expect developments, Watson.’

‘When?’

’Now—­within a few minutes.  I dare say you thought I acted rather badly to Stanley Hopkins just now.’

‘I trust your judgment.’

’A very sensible reply, Watson.  You must look at it this way:  what I know is unofficial, what he knows is official.  I have the right to private judgment, but he has none.  He must disclose all, or he is a traitor to his service.  In a doubtful case I would not put him in so painful a position, and so I reserve my information until my own mind is clear upon the matter.’

‘But when will that be?’

’The time has come.  You will now be present at the last scene of a remarkable little drama.’

There was a sound upon the stairs, and our door was opened to admit as fine a specimen of manhood as ever passed through it.  He was a very tall young man, golden-moustached, blue-eyed, with a skin which had been burned by tropical suns, and a springy step, which showed that the huge frame was as active as it was strong.  He closed the door behind him, and then he stood with clenched hands and heaving breast, choking down some overmastering emotion.

‘Sit down, Captain Crocker.  You got my telegram?’

Our visitor sank into an armchair and looked from one to the other of us with questioning eyes.

’I got your telegram, and I came at the hour you said.  I heard that you had been down to the office.  There was no getting away from you.  Let’s hear the worst.  What are you going to do with me?  Arrest me?  Speak out, man!  You can’t sit there and play with me like a cat with a mouse.’

‘Give him a cigar,’ said Holmes.  ’Bite on that, Captain Crocker, and don’t let your nerves run away with you.  I should not sit here smoking with you if I thought that you were a common criminal, you may be sure of that.  Be frank with me and we may do some good.  Play tricks with me, and I’ll crush you.’

‘What do you wish me to do?’

To give me a true account of all that happened at the Abbey Grange last night—­a true account, mind you, with nothing added and nothing taken off.  I know so much already that if you go one inch off the straight, I’ll blow this police whistle from my window and the affair goes out of my hands forever.’

The sailor thought for a little.  Then he struck his leg with his great sunburned hand.
