Thinking about the Text
“A mystery I propose to explain.” What is the mystery the speaker proposes
to explain?
The mystery that Gerrard proposed to explain was the story he made up to dodge the intruder and escape him. The story was that Gerrard himself was a criminal like the intruder. He asked why else would he not meet any trades people and was all over different places. When things went wrong with him, he had committed a murder and got away. Unfortunately, one of his men had been arrested and certain things were found which his men should have burnt. He said that he was expecting some trouble that night and therefore, his bag was packed and he was ready to escape.
