Lutt looked around him at the office, all of it much as he had found it the night of his father's death. He thought he had uncovered most of the traps but the Listening Post still daunted him. There was a pattern to the traps, Lutt thought, but he could not put it into words.

The guards flatly refused to enter L.H.'s premises.
