The Last Detective

The judge looked faintly amused. He leaned forward, his chin propped on his right hand. 'Sir Job?'

Some hurried shuffling of papers at the prosecution table underlined their confusion. 'At this point, m'lord, we propose to move on to the chief inspector's evidence-in-chief.'

'Then I suggest you do.'

The next hour and fifty minutes was an exercise in damage limitation, a painstaking recapitulation of the police investigation. By switching back to the discovery of the body in Chew Valley Lake and plodding systematically through the process that had led to Dana's indictment, Sir Job contrived point by point to rehabilitate Wigfull as a credible witness.

To Wigfull's credit, his testimony was equal to the challenge. He spoke with restored assurance, making a point of facing the jury as he gave his responses, and his language was simple and direct. He didn't hesitate again. He must have been aware that Diamond was watching from the public gallery, yet he described the first phases of the inquiry, when Diamond had been in charge, with impeccable recall – the search of the lakeside and the delay in identifying the body; the television and press appeals for information; and how Professor Jackman had eventually come forward and identified the body. Sir Job took him through the search of John Brydon House, the interviews with Jackman and the transatlantic phone conversation with the American academic, Dr Junker (an affidavit from Junker had been filed by the prosecution). Wigfull explained how checks had been made at University College and with Air France that established an alibi for Jackman, and how the focus of the investigation had then switched to Dana.

'What happened when you went to interview her?'

'She ran out of the back of the house. I gave chase, but she got into the Mercedes and drove away. It happened that she met another car in a narrow road near the house -met it head-on. There was a slight collision.'

'She was unhurt?'

'Yes, sir.'

'And did she admit to running away from the police?'

'Her words were, "I was trying to escape."'

So it went on through the morning, this process of assembling a case that would allow no reasonable doubt. Sir Job omitted nothing. He took Wigfull through the interview of Dana and established that she had insisted she had no more to tell when in reality there had been much more to come. He plotted the stages of her disclosures, showing how she'd eventually admitted to having visited the Jackman's house on the morning of the murder and had seen Geraldine lying dead in bed. Finally, he testified that when the reports had come back from the forensic lab confirming that the body had been placed in Dana's car boot, he had formally charged her with murder in the presence of her solicitor.

It was 12.50 when Sir Job concluded the examination-in-chief. The court adjourned for lunch. Dana, ashen after the morning's ordeal, was led down to the cells.

Siddons, her solicitor, was waiting for Diamond at the foot of the stairs from the public gallery. 'Do you have a few minutes? Mrs Bargainer would so like to meet you.'

'Her memory can't be too hot,' Diamond commented. 'She cross-examined me in this court six months ago.'

They invited him to join them for lunch across the road. Out of her wig and gown, Lilian Bargainer passed for one of the mainstays of the lounge bar, drinking dry sherry from a schooner and dragging at a cigarette that she held between thumb and forefinger. 'God, what a production old Claws is making of it,' she said. 'He's working on the principle that if Wigfull talks for long enough the jury will forget the balls-up of the missing letters. Never fear – I'll remind 'em.' She gripped Diamond's sleeve. 'Peter, old sport, I owe you one for that. What are you drinking?'

'Orange juice,' said Diamond, tapping his head-bandage.

She pushed a ten-pound note at Siddons. 'Be an angel. Get one for yourself. I mean a beer or something. And see what food there is.' Alone at the table with Diamond, she said, 'I want to tap your brain.'

'Gently, if you must.'

'I cross-examine Johnny Wigfull this afternoon. I intend to keep it short and devastating, but I mustn't miss anything. What are the weak points in the evidence?'

'I wouldn't trouble with the weak points if I were you,' Diamond told her. 'Go for the strong one.'

'The body in the boot?'

'Right. If you hadn't suggested this meeting, I was going to whisper in Siddons' ear.'

'Ah – so you know something?'

'I wouldn't put it so strongly as that – particularly after brain surgery. I don't know how reliable the little grey cells are, but they've been working overtime to catch up.'

He wasn't really underselling the importance of what he was about to tell her. He quietly relished this moment as much as he relished the sensation to come in court. For all her hail-fellow manner, Lilian Bargainer had a shrewd brain. She would appreciate this. She would understand its significance, a triumph of canny detection over the men in white coats.

'Get to the point, my love. Time's at a premium.'

'If I'm right about this, there's a detail – an important detail-you can check with your client. She won't appreciate the significance, by the way.'

'She's in no shape of mind to appreciate anything, sport, but I'm willing to try.'

'Ask her to cast her mind back to that morning she took Matthew up to John Brydon House and saw the blond man walking out on Geraldine.'

'The pusher – Andy Coventry?'

'Yes. In her statement, she told me he appeared familiar at the time, but she couldn't place him. I think we may be able to refresh her memory. Ask her if she could have seen him swimming.'

'Swimming? You'd better explain, you cryptic old bugger.'

Wigfull looked apprehensive as he entered the witness box again. With good reason. His rehabilitation had owed everything to Sir Job Mogg. Lilian Bargainer wouldn't be wearing velvet gloves for the cross-examination. Up in the public gallery, however, Peter Diamond was in a forgiving mood. The last words he had spoken to Mrs Bargainer were, 'Wigfull's not a bad detective. He's wrong, but he's not bad. You don't have to wipe the floor with him.'

She was on her feet. 'Chief Inspector, I shan't detain you long. You've given the court a copious account of your investigation, but you neglected to mention that the late Mrs Geraldine Jackman was a user of cocaine. Did you not consider this of relevance?'

'It came to our notice only recently,' Wigfull stated with a smoothness suggesting he had anticipated the question.

'But it doesn't affect the present case?'

'That is correct.'

'That is your judgement.' She turned towards the jury and rolled her eyes upwards as if in despair of the police. Then she swung back to Wigfull. 'There is one other matter I should like to clarify, and that concerns the interrogation of the accused, Mrs Didrikson. She was taken by ex-Superintendent Diamond and yourself to Bath Central Police Station for questioning on Tuesday, 10 October. Am I right? You may refer to your notes. I want to get this clear.'

Wigfull produced his notebook and thumbed through it.'10 October. Yes.'

'She was detained overnight? Is that correct?'

'Yes.'

'And on 11 October her car was collected for forensic examination?'

'Yes – but with her permission.'

'Granted. Your personal conduct towards Mrs Didrikson cannot be faulted. I believe you went so far as to notify her employer, Mr Buckle, that she would not be able to drive him in the morning.'

Wigfull agreed modestly, 'That's true. I did.'

'A very considerate thing to have done, if I may say so,' Mrs Bargainer complimented him.
