'Selden - the murderer?' I said. 'And why do you signal to him at night?'
'My husband takes him food and clothes,' said Mrs Barrymore. 'We signal to tell him my husband is coming.'
'I understand,' said Sir Henry. 'He is your brother; you must try to help him. Go to your room. We will talk about this in the morning.'
The Barrymores left the room.
Sir Henry turned and spoke to me. 'I am sorry for them, but Selden is a murderer. I must try to catch him.'
'Look!' I said. 'Look out of the window. There is a light on the moor.'
Sir Henry looked. A small light was shining on the moor. It was near High Tor.
'That's him!' said Sir Henry. 'Come, Dr Watson, we will go to that light. Bring your revolver.'
