'I saw Mister Hyde go in by the old dissecting-room door, Poole,' I said. 'Is that right, when Doctor Jekyll is from home?'

'Quite right, Mister Utterson, sir,' replied the servant. 'Mister Hyde has a key.'

'Your master seems to repose a great deal of trust in that young man, Poole,' I mused aloud.

'Yes, sir, he do indeed,' said Poole. 'We have all orders to obey him.'

'I do not think I ever met Mister Hyde?' I asked, seeing what the butler would feel able to tell me without pressing him to betray his master.

'O, dear no, sir. He never dines here,' replied the butler. 'Indeed we see very little of him on this side of the house; he mostly comes and goes by the laboratory.'

That certainly fit with everything I knew about Mister Hyde, and drew an end to the questions I could think of. 'Well, good-night, Poole.' I gathered my coat around me.

'Good-night, Mister Utterson.'
