You ask the maid what she saw that evening.
"I saw Simon Hayes coming out of the conference room," she said. "There was no one else in the conference room and there was no conference meeting organised for 5.45pm. That's when I saw him."
"Did he have anything in his hands?" you say.
"No," she replies, "but he was panting for some reason."
"Was there anyone chasing him?" you ask. "I don't know," she says.
