more than one room involved?"
Macaskin nodded. He went over to a second table which abutted the wall and picked up several folders and a roll of paper. The latter he smoothed out on the tabletop, revealing a more than adequate floor plan of the house. It was extraordinarily detailed, considering the time constraints that had been put upon him at Westerbrae this morning, and Macaskin smiled at his finished work with real pleasure. Weighing it down at either end with the folders, he gestured to the right.
"Victim's room is on the east side of the house." He opened one of the folders and glanced at his notes before continuing. "One side of her was the room belonging to Joanna Ellacourt and her husband...David Sydeham. Other side was a young woman...here it is. Lady Helen Clyde. It's this second room that's been sealed off." He looked up in time to see the surprise on all three of the London faces. "You know these people?"
"Just Lady Helen Clyde. She works with me," St. James replied. He looked at Lynley. "Did you know Helen was coming to Scotland, Tommy? I thought she'd planned to go to Cornwall with you."
"She begged off the trip last Monday night, so I went alone." Lynley looked at the fl oor plan, touching his fingers meditatively to it. "Why has Helen's room been sealed?"
"It adjoins the victim's room," Macaskin answered.
"Now there's a piece of luck," St. James said with a smile. "Leave it to our Helen to get herself booked right next door to a murder. We'll want to talk to her at once."
Macaskin frowned at this and leaned forward, placing himself squarely between the two men to get their attention with a physical intrusion before he went on with a verbal one. "Inspector," he said, "about Lady Helen Clyde." Something in his voice arrested the other two men's conversation. Warily, they looked at each other as Macaskin added grimly, "About her room."
"What about it?"
"It appears to be the means of access."
LYNLEY WAS STILL trying to understand what Helen was doing with a group of actors in Scotland when Inspector Macaskin imparted this new piece of information.
"What makes you think that?" he asked at last, although his mind was taken up mostly with his last conversation with Helen, less than a week ago in his library in London. She'd been wearing the loveliest jade-coloured wool, had tasted his new Spanish sherry- laughing and chatting in that light-hearted way of hers-and had rushed off promptly to meet someone for dinner. Who? he wondered now. She hadn't said. He hadn't asked.
Macaskin, he noted, was watching him like a man who had things on his mind and was merely waiting for the right opportunity to trot them all out.
"Because the victim's hall door was locked," Macaskin replied. "When Mary Agnes tried to rouse her without success this morning, she had to use the master keys-"
"Where are they kept?"
"In the office." Macaskin pointed to the map. "Lower floor, northwest wing." He continued. "She unlocked the door and found the body."
"Who has access to these master keys? Is there another set of them?"
"Only one set. Just Francesca Gerrard and the girl, Mary Agnes, use them. They were kept locked in the bottom drawer of Mrs. Gerrard's desk. Only she and the Campbell girl have keys to get into it."
"No one else?" Lynley asked.
Macaskin looked thoughtfully down at the plan, moving his eyes along the lower northwest corridor of the house. It was part of a quadrangle, possibly an addition to the original building, and it grew out of the great hall not far from the stairway. He pointed to the first room in the corridor.
"There's Gowan Kilbride," he said pensively. "A kind of jack-of-all-trades. He could have got to the keys had he known they were there."
"Did he know?"
"It's possible. I gather that Gowan's duties don't generally range to the upper floors of the house, so he'd have no need of the master keys. But he might have known about them had Mary Agnes told him where they were."
"And might she have done so?"
Macaskin shrugged. "Perhaps. They're teenagers, aren't they? Teenagers sometimes try to impress each other all sorts of silly ways. Especially if there's an attraction between them."
"Did Mary Agnes say if the master keys were in their normal place this morning? Had they been disturbed?"
"Apparently not, since the desk was locked as usual. But it's not the kind of thing the girl is likely to have noticed. She unlocked the desk,
