There was, however, one highly interesting fact which emerged from the expert’s investigation of Preston’s computer activities. To most people, computer printouts are identical. Whereas the sheets from typewriters were almost as individual as fingerprints in the hands of an expert, computer print-outs are much more uniform. But not to the modern IT forensic specialist; Rushton was able to relay a most interesting discovery.
The death threats that had excited very different reactions in Marjorie Dooks, Sue Charles and Ros Barker had all been produced on the PC and printer in the study of Peter Preston. He had presented the copy, which he maintained was a threat to his own life, purely in an attempt to divert suspicion from himself as the originator of the letters.
‘So Ros Barker was right,’ said Bert Hook thoughtfully. ‘She thought those letters were the sort of stupid thing Peter Preston might perpetrate.’

Policemen make good gardeners. Like many other comfortable assumptions, that has rarely been subjected to the harsh test of statistics. But the idea persists, even though the advance of technology has made modern policing a vastly different task from what it was fifty years ago, when the tradition took root. Perhaps it is the awful things they are compelled to witness during their professional day that makes coppers enjoy something as basic, innocent and consoling as gardening. Perhaps cultivating the soil and following the eternal cycle of the seasons helps to keep things in proportion. It must be instinctive, for few policemen are aware of Voltaire’s maxim that, whatever goes on elsewhere, ‘Il faut cultiver notre jardin’. John Lambert knew the quote and embraced it, but then Chief Superintendent Lambert was what is commonly known in police parlance as ‘a clever bugger’.
He and Hook gave the garden around Sue Charles’s bungalow their cautious approval. Wallflowers offered their scented splendour in the border that ran the length of the front of the building, divided only by the path along which the pair now moved to the front door. The roses at the edge of the well-trimmed lawns were full of swelling buds, reminding them that the glories of late spring and summer were at hand. A cat dozed in the sun beneath the porch. ‘Good afternoon, Roland!’ said Bert Hook affably. The cat gazed at them disapprovingly for several seconds. He was apparently unimpressed by Bert’s recall of his name. Having completed his scrutiny, he disappeared round the side of his home with a quick lash of his tail.
Sue Charles opened the door and instantly recognized DS Hook. She seemed pleased to see him again as he introduced John Lambert. It was an unusual reception for her visitors, who were more used to being received with hostility or a nervous caution. She had tea and homemade cake ready for them, another plus factor in Bert’s Hook’s assessment. He complimented her on her garden as she poured the tea. Sue said, ‘We’re lucky here — good Gloucestershire soil, with few stones and only a little clay. I have an old friend who comes in to do some of the heavier jobs when I need him, but I still enjoy doing most of the propagating and planting myself. I did that even when George was alive. He wasn’t as interested as I was, and he had a time-consuming job.’
Lambert said, ‘Gardeners are like farmers, in my experience. Not many of them admit to having the ideal soil as you do, and the weather is never quite right.’ He was watching her closely through the pleasantries. This alert, competent grey-haired woman of sixty-eight was a possible killer, until cleared of suspicion, however unlikely that seemed. Even if she was dismissed as a suspect, they still needed to know how reliable she was, both as a witness of events leading up to Preston’s death and as a judge of character where other people were involved. Initial impressions were favourable. He could see her impressing judge and jury in court with her maturity, intelligence and precision.
As if she were reading his thoughts, she said, ‘I’m sure you’ll find who killed poor old Peter Preston pretty quickly.’
Lambert smiled and moved eagerly into the main purpose of their visit. ‘You speak of him with some affection. We’ve been told that you had good reason to dislike him.’
‘I suppose I had. But I had a soft spot for old Peter and his posturings. I felt sorry for him, in many ways. He was one of those people who’ve done good work in their youth but seem unable to move on. He was irritating at times, even insulting, but I couldn’t take him seriously enough to be really offended.’
‘Even when he denigrated your own work?’
She smiled at him, an unexpected hint of mischief in the blue eyes beneath the grey hair. ‘You have an eye for human weakness, Mr Lambert. Few of us are completely objective about our own work. If you want to hurt someone who writes or paints or plays music, the thing to go for is their work.’
‘Which we hear Preston did with your detective novels.’
‘Do you, indeed? Well, I suppose Peter never made any secret of his prejudices. He enjoyed parading them in public. I disliked him when he did that — but dislike isn’t an emotion which translates into hatred and murder.’
‘I agree. But I expect we shall find a lot of people who disliked Mr Preston and very few who moved on from that to a murderous hatred.’
‘I shall be interested in the details of your investigation. I have what I suppose you could call a professional interest in this. I write about murder all the time, but I’ve never been even remotely connected with a serious crime before.’
‘Most murders are either gangland killings or domestic incidents among the victim’s family, as you probably know.’
‘I do, yes. I study the statistics. But one of the rules of writing is to deal with what you know, and I’ve no experience of gangland criminals, drugs, or prostitution.’ Sue was rather enjoying her exchanges with a real chief superintendent. This man didn’t seem to have much in common with the tortured psyches of most fictional creations. ‘Speaking of domestics, I do hope poor Edwina is coping with Peter’s death. She was very shocked when she was here yesterday morning, but that was only to be expected.’
‘Mrs Preston came here yesterday morning?’
‘Yes. I found her looking quite distracted in the supermarket car park. That’s how I heard about Peter’s death. I brought her back here for coffee and sympathy.’
It was curious that Edwina Preston hadn’t mentioned that when they’d talked to her later in the day. But no doubt she’d been confused by the speed of events after arriving home to hear of Peter’s death. Lambert transferred his attention swiftly back to the crime novelist and decided that it was time to test this likeable woman’s composure. ‘Where were you yourself on Tuesday night, Mrs Charles?’
‘I was here. Alone, as I am on most evenings.’
‘Is there anyone who could confirm this for us?’
‘I’m afraid there isn’t.’ She looked affectionately at her cat, who had just strolled into the room with tail erect, glaring resentfully at the two large men on the sofa. ‘I can hardly invoke Roland to attest my alibi, can I?’ She watched Hook making a note, glanced at Lambert’s long, grave face, and said, ‘I’m sorry, I know this is serious stuff for you. And I’d obviously like to absolve myself as a candidate for murder, but I can only report the truth. The fact is that I venture out very little in the evenings. People tend to invite their visitors in pairs, so my social life has become constricted in the ten years since my husband died.’
‘We seem to be agreed that Preston was a man with many enemies. It’s almost material for one of your whodunits, Mrs Charles.’
‘Indeed. Except that I never put real people into my books. The other difference is that this situation is not imaginary but deadly serious. I still find it difficult to believe that Peter is dead, and even more so to imagine that someone took a pistol to his house and shot him. I believe that is what happened.’
