Tregower was regarding her with guarded eyes. ‘Perhaps not,’ he agreed dryly. ‘No woman is worth that kind of sacrifice. Not even you, Diane.’
Clenching her teeth, Sara scrabbled round in her handbag and brought out her driving licence. ‘There,’ she said, thrusting it at him. ‘My name is Sara Fortune. That’s my licence.’
He took the plastic folder without protest, and flicked it open. ‘Sara Fortune,’ he read, with dark eyebrows slightly upraised. ‘Flat 3, Dolphin Court, West Kensington. Hmm, very interesting. Who is Sara Fortune, by the way? Your secretary? Wilmer’s?’
‘Lance Wilmer is my father’s cousin,’ declared Sara angrily. ‘I tell you, I’m Sara Fortune. Why won’t you believe me?’
Michael Tregower’s brows descended. ‘Did you honestly think producing a driving licence would convince me? My dear Diane, it occurs to me that if you’d had an accident around here, it might have been hard to explain exactly what you were doing in the area. People in your position often travel incognito, don’t they? So—you’ve adopted Miss Fortune’s identity, whoever she may be.’
Sara sighed. ‘Haven’t you ever seen Diane? Haven’t you ever met her? I’m nothing like her.’
‘Slim, blonde, green eyes; looks younger than her years …’ he shrugged. ‘You would seem to fit the description very well. Besides,’ his mouth tightened ominously, ‘Adam had a picture of you in his wallet. You’re Diane Tregower all right. I’d know that innocent face anywhere!’
Sara shook her head, thinking desperately. ‘But don’t you see?’ she said at last. ‘The picture Ad—your brother kept in his wallet was probably taken ten years ago. Diane’s changed. She’s older now. Where is the picture? Let me see it.’
‘I don’t have it,’ he declared coldly. ‘Adam would never let it out of his hands. After he was dead, it was buried with him.’
‘Oh.’ Sara felt as if the bottom was dropping out of her world. Then another idea came to her. ‘Ring,’ she said. ‘Telephone London. I have Diane’s number. Speak to her. See for yourself that she’s really there, not here. She—she’s appearing in a play at the moment.’ She glanced nervously at her wrist watch. ‘Ring the theatre. Surely that will convince you.’
He stared at her beneath lowering lids. ‘How do I know you don’t have someone waiting at the theatre, depending on this call?’
‘How could I?’ Sara was desperate. ‘How could I know what might happen?’
He scowled. ‘My note—the note you thought came from Adam was explicit enough. Come alone, it said. Tell no one where you’re going.’
Sara gulped. ‘Well—well, surely then, I wouldn’t—have told anyone …’
He was obviously hesitating, and she pressed a finger on her palpitating pulse. No excitement! she thought wryly. Dear God, she had had more excitement in the last half hour than she had had in her whole life before. She ought to be dismayed. But she wasn’t. She had never felt the adrenalin flooding along her veins as it was doing at the moment, and the exhilaration that accompanied it was intoxicating.
‘All right,’ he said at last, when she was beginning to give up hope of him ever agreeing to make the call. ‘What’s the number of the theatre? I’ll speak to the manager.’
Sara scribbled the number on a slip of paper and handed it him. She supposed, belatedly, that she ought to have pretended ignorance, or at least hesitated before writing down the figures. But it was too late now. He was already crossing the hall to pick up the green telephone that rested on the oak chest.
There was a moment’s delay while he contacted the operator at Torleven, and then Sara heard the reassuring burr of the bell ringing in the manager’s office. It seemed to ring for ages before it was answered, but when the receiver was lifted, she found herself holding her breath as Michael Tregower made his enquiry.
‘Not there?’ he said, a moment later, swinging round to stare grimly at Sara. ‘What? Taken ill? I’m sorry. Do you know when she’ll be back? Oh—I—er—I’m just a friend. A friend of a friend, as you might say. No. Sorry. Yes, of course. Goodbye.’
As the receiver was replaced, Sara felt her tongue clinging to the roof of her mouth. She didn’t have to be told that Diane wasn’t in the building. Even without Michael Tregower’s words, his expression said it all.
‘There’s panic on, apparently,’ he declared without emotion. ‘Your understudy’s had to take over at the last moment, and people are demanding their money back. An unexpected illness, so your agent tells them. They don’t know when you’ll be able to return.’
Sara moved her head in a helpless, negative gesture. ‘Diane—Diane must have planned this,’ she said incredulously. ‘She must have known I might try to get in touch with her …’
‘Oh, come on.’ He sounded really impatient now. ‘Don’t you think this has gone on long enough? When you passed out just now I should have realised that no stranger was likely to react so positively. You were scared, Diane, admit it! Scared out of your tiny mind! But not half as scared as you ought to be now, knowing I know that you’ve burned your bridges behind you.’
Sara felt unutterably weary suddenly. It had all been too much for her. Much too much. The retort that had she known Diane would not be there, she would hardly have suggested ringing the theatre, trembled on her lips, but was never spoken. Michael Tregower would doubtless decide she had only been playing for time, for whatever defence she raised, he tore it down ruthlessly.
‘I think we should eat, don’t you?’ he declared coldly, and with a helpless movement of her shoulders, she implied consent.
The dining room was at the back of the house, and here the blinds had been drawn to allow the last light of the evening to penetrate its shadowy corners. A lamp on a long sideboard gave illumination, and the table was laid with a white damask cloth and silver cutlery. There was a savoury quiche, a dish of cold meats, a bowl of tossed salad, and some crusty rolls. To follow there was a strawberry gateau, and Sara wished she felt more able to do justice to it. But her mind buzzed with the possibilities of what Michael Tregower intended to do with her—with Diane—and it was difficult to concentrate on anything with that nagging anxiety bringing a hectic flush to her cheeks.
‘Relax,’ he remarked unsympathetically, leaving her to seat herself on one of the tapestry-covered chairs. ‘For a woman of your age and apparent experience, you’re ridiculously sensitive. Or is that an act, too? How does one tell?’
Sara subsided on to the chair at the opposite end of the table from the one he had taken, and made no attempt to answer him. But her silence was evidently no more acceptable than her diffidence, for he stifled a curse as he rose again and came to take the seat at right angles to her.
‘Surely this is cosier,’ he remarked with cold mockery, and her hands tightened automatically in her lap.
She supposed she ought to tell him that as well as being someone else, she was also suffering from a rare heart disease that, while allowing her to lead a normal life in ordinary circumstances could, given sufficient stimulation, cause valvular failure and, ultimately, death. It was a condition she had lived with all her life, or at least as long as she could remember. Rheumatic fever when she was scarcely out of infancy had affected her heart, narrowing the valves and preventing them from closing properly. Regular care and the use of drugs had minimised the effects of the disease, but it was always there, and in cases of extreme stress her heart could cease to function entirely. Sara seldom talked about it. Indeed, if anything, she was ashamed of the weakness that her mother had guarded so vigilantly. After her mother’s death, she had felt a sense of freedom from the knowledge, but Tony’s defection and her subsequent withdrawal had reminded her of her vulnerability.
Now this man, Michael Tregower, was tormenting her, goading her, threatening her with she knew not what. And he had no idea of the risks he was running
