Wolfie shook with alarm as he stared at the constables' faces, his trust in Bella running like sawdust from his knees. Hadn't he told her Fox wasn't there? What would these men do when they found the bus empty? Bella should never have let them in… should never have mentioned his mother… they'd search for bruises and take him away…

Martin saw the fear in his face and squatted on his haunches to bring himself to the child's level. "Hi, Wolfie. Do you want to hear a joke?"

Wolfie shrank against Bella's legs.

"What do you call two rows of cabbages?"

No response.

"A dual cabbageway." Martin studied Wolfie's unsmiling face. "Heard it before, eh?"

The child shook his head.

"You don't think it's funny?"

A tiny nod.

Martin held his gaze for a moment, then dropped him a wink and stood up. The boy's fear was palpable, although whether he was afraid of policemen per se or of what a search of the camp might find, it was difficult to say. One thing was certain. If Bella had been looking after him for any length of time, he wouldn't be dressed in such inadequate clothing for a winter's night and he wouldn't be looking half-starved.

"Right," he said, "do you want to introduce us to your friends, Bella? My colleague here is PC Sean Wyatt, and you might like to make it clear that we're not interested in anything except the intruder at Shenstead Farm."

She nodded, taking Wolfie's hand firmly in hers. "Far as I know, there's nothing to find, Mr. Barker," she said with as much conviction as she could muster. "We're all families and we started this project the way we mean to go on… doing it by the book so the people round about wouldn't have nothing to complain about. There's the odd bit of dope stashed away, but nothing worse."

He stood aside for her to lead the way, noticing that she chose to start with the bus to the right of the semicircle-the most distant-where light leaked from cracks around the window blinds. He, of course, was more interested in the bus to the left, which drew Wolfie's eyes like magnets and appeared to be in total darkness.

DS Monroe passed the campsite on his way to Shenstead House and saw figures milling in front of the buses, thrown into relief by the headlamps of his colleagues' parked car. It was a reasonable assumption that the face at the window belonged to a newly arrived traveler, but he intended to exploit Mrs. Weldon's insistence that her friend had turned "peculiar" since she visited the site. It was an excuse of sorts to interview Mrs. Bartlett because there was nothing else to investigate. No complaint had been made against her, and the file on Mrs. Lockyer-Fox had been closed for months.

Nevertheless, Monroe was curious. Ailsa's death continued to play on his mind, despite the coroner's verdict. He had been the first on the scene and the impact of the sad little body, propped against the sundial, wearing a thin nightdress, a man's threadbare dressing-gown, and a pair of Wellington boots had been powerful. Whatever the final conclusion, it had always felt like murder to Monroe. The bloodstains a yard from the body, the incongruity of insubstantial nightclothes and solid Wellingtons, the inevitable conclusion that something had disturbed her sleep and she had ventured outside to investigate.

He had played down Prue's hysterical conclusion that Eleanor's "peculiarity" meant the face at the window was Darth Vader's-"You have a habit of putting two and two together and making five, Mrs. Weldon"-but he was interested in the coincidence of the travelers' arrival and the falling-out between the women. He was too experienced to assume a connection without evidence, but the possibility that one existed remained at the back of his mind.

He drew to a halt at the entrance to Shenstead Manor, still undecided about whether to talk to Colonel Lockyer-Fox before he spoke to Mrs. Bartlett. It would help to know exactly what the woman had been saying, but if the Colonel refused to cooperate then Monroe's already limited excuses for questioning the woman would vanish. He needed an official complaint, a fact that the Colonel's solicitor would certainly point out, assuming he was the one advising reticence.

It was this reticence that really intrigued Monroe. The idea that lodged in his mind-strengthened both by the need for a voice distorter and the lawyer's remark to Mrs. Weldon that her friend's knowledge of the family was very detailed-was that Darth Vader was closely related to the Colonel.

And he kept remembering that, in the hours following his wife's death, the Colonel had accused his son of murdering her…

It was julian who answered the bell. He looked at Monroe's warrant, listened to his request for an interview with Mrs. Bartlett, then shrugged and pulled the door wide. "She's in here." He ushered him into a sitting room. "The police want to talk to you," he said indifferently. "I'm going to my study."

Monroe saw the alarm on the woman's face change rapidly to relief as her husband announced his intention of leaving. He moved to bar Julian's exit. "I'd rather you didn't, sir. What I have to say involves everyone in this house."

"Not me it doesn't," Julian retorted coolly.

"How do you know, sir?"

"Because I only learned about these damn phone calls this afternoon." He stared at the sergeant's unresponsive face. "That's why you're here, isn't it?"

Monroe glanced at Eleanor. "Not precisely, no. Mrs. Weldon reported an intruder at Shenstead Farm and she seems to think your wife knows who it might have been. It happened shortly after Colonel Lockyer-Fox and his solicitor played some tapes to her of Mrs. Bartlett and a man making identical allegations against the Colonel, and Mrs. Weldon believes that this man was her intruder. I'm hoping Mrs. Bartlett can throw some light on the situation."

Eleanor looked as if she'd been sandbagged. "I don't know what you're talking about," she managed.

"I'm sorry. I obviously didn't explain myself very well. Mrs. Weldon believes her intruder to be the man who's behind a hate campaign against Colonel Lockyer-Fox. She further believes him to be one of the travelers camped in the wood above the village… and says you must have spoken to him this morning as you've been acting very strangely ever since. He uses a voice distorter to disguise his voice, but she says you know who he is."

Eleanor's mouth turned down in an unattractive horseshoe. "That's ridiculous," she snapped. "Prue's a fantasist… always has been. Personally, I think you should question whether an intruder ever existed because she's not above inventing one to get a little attention. I suppose you know she's had a row with her husband and he's talking about divorcing her?"

Monroe didn't, but he wasn't about to admit it. "She's frightened," he said. "According to her, this man mutilated the Colonel's dog and left him outside for the Colonel to find."

Her eyes darted nervously toward her husband. "I don't know anything about that."

"You knew the dog was dead, Mrs. Bartlett. Mrs. Weldon says you were pleased about it-" he paused for emphasis- "something to do with chickens coming home to roost."

"That's not true."

Julian's reaction was to throw her to the wolves. "It sounds like you," he said. "You never liked poor old Henry." He turned to Monroe. "Sit down, Sergeant," he invited, pointing to an armchair and taking another for himself. "I hadn't realized there was any more to this-" he made a gesture of distaste-"humiliating story than my wife and Prue Weldon making phone calls. It seems I was wrong. What exactly has been going on?"

Monroe watched Eleanor's face as he took the other chair. She was a different animal from her plump friend-stronger and tougher-but catastrophe was showing in her eyes just as clearly as it had been in Prue's.
