"I heard it--I was in the hall," said Arnold, "and I was afraid. I admit it, Fane, I was terribly afraid."
"I guessed you would be. You left the house. I saw the policeman lean over the gate to listen. I saw you join him. I saw you walk away. Then I thought I would escape. When you were gone with the officer, I stole out. I passed along a by-street. I saw a motor----"
"My car," said Tracey, "and you took it to Charing Cross."
"I did," nodded Fane, "then I left it there and caught the underground railway to Liverpool Street, where I took the express to Southend. The rest you know."
"Not who killed Mrs. Brand," said Arnold.
Fane considered. "I can't tell you who did," he said; "she was dead before I came, so those who came into the house after ten could not have killed her."
"Do you know who they were?"
"No! I heard footsteps."
"How do you know there were two?"
"I only think so. There might have been only one person. I can't say, I was not in a state to think. I hid, and then all happened as I say. I don't know who killed my wife. I got back to Southend and afterwards heard the body had been discovered. I came to town and bluffed out the whole matter with that fool of a Derrick. When I heard about the Hampstead house being found I went there before Derrick came, and removed everything, as I said."
