## Key lines

> I locked it myself. I locked it myself. It was there at eight o’clock, and who could get at it since then? Why, no one but myself knew about it. How could anyone else have known?

Felix insists he locked the cask and cannot understand how anyone else could have taken it.

_Felix's repeated assertion highlights his shock and the mystery of the theft._

> It is our business to know these things. I knew all about how you got the cask away from the docks also.

Burnley reveals that the police were already tracking Felix's movements.

_Burnley asserts the effectiveness of police surveillance._

> The fourth nail on the lefthand side is gone. That alone might be a coincidence, but if you compare the wear of the other nails and of the leather you will see they are the same beyond doubt.

Burnley points out that identical wear patterns in the footprints prove they were made by the same person.

_Burnley uses detailed footprint analysis to build his case._
