client was arrested on the same night that his father’s body was discovered. Is that right, Inspector?’ asked Swift.
‘Yes. On the fifth of June. He was arrested on the basis of what we were told by Mr Ritter at the scene. That the defendant had unlocked the door of the study from the inside to let him in.’
‘And Mr Ritter was the first to respond to my client shouting in the study?’
‘I don’t think I can answer that, I’m afraid. I can only tell you the reason why we arrested Stephen Cade. I can’t give direct evidence about what happened in the house before I arrived.’
‘Of course he can’t. You shouldn’t need a policeman to tell you that, Mr Swift,’ said Judge Murdoch irritably. ‘How can the inspector know who shouted, or if anyone shouted for that matter?’
‘He can’t, my lord. I’m sorry. Let me ask you about the cause of death, Inspector. Only one bullet had been fired from the pistol that you found on the side table. Is that right?’
‘Yes.’
‘And it had entered the professor’s forehead?’
‘Yes. And lodged in his brain.’
‘To use a popular expression, he’d been shot between the eyes.’
‘Just above a point between the eyes.’
‘Thank you. It was an execution-type shooting. That’s my point. Would you agree with that description?’
‘Yes, I suppose so.’
‘To achieve that kind of precision with a bullet, wouldn’t you need considerable skill as a marksman?’
‘I don’t know. I’m not an expert.’
‘No. Quite right, Inspector. You’re not,’ said the judge. ‘Is there evidence of the distance from which the shot was fired, Mr Thompson?’
‘About twelve feet according to the report, my lord,’ said the prosecutor, reading from one of his many files.
‘I see. Not exactly a great distance, Mr Swift.’
‘No, my lord. I’ve made my point. I’ll move on. You’ve told us about Mr and Mrs Ritter, Inspector. Who else was in the house on the night of the murder?’
‘The defendant’s girlfriend, Mary Martin; his elder brother, Silas Cade; and Sasha Vigne.’
‘Who’s she?’
‘She was Professor Cade’s personal assistant. The professor had a large collection of valuable manuscripts, which were housed in a gallery on the first floor of the main body of the house. It’s my understanding that she helped the professor with cataloguing them and with research for a book that he was writing on medieval art history.’
‘I see. Now where were these other people located in the house?’
‘Everyone was in the drawing room when I arrived. Awaiting questioning.’
‘No, that’s not what I meant, Inspector. Where were their bedrooms?’
‘All on the first floor of the west wing. Only the Ritters and Professor Cade himself slept on the east side.’
‘And what about the grounds? They’re quite extensive, aren’t they?’
‘Yes. There are stone terraces around the house with lawns beyond.’
‘And quite a lot of trees as well?’
‘Yes.’
‘The drive is tree lined, is it not?’
‘Yes, it is.’
‘We don’t need a National Trust tour of the Moreton Manor gardens, Mr Swift,’ interrupted the judge. ‘What’s the point you’re trying to make?’
‘That an intruder could hide in the trees, my lord.’
‘If there was an intruder. You’d better ask the inspector about the security system. It looks fairly state-of-the-art in the photographs.’
‘I was just about to,’ said Swift, keeping a smile stretched across his features by an extraordinary effort of will. ‘Please do as his lordship asked, Inspector. Tell us about the security system.’
‘The main gate is the only exit from the grounds,’ said Trave. ‘A Tarmac drive leads up to it from the courtyard. Otherwise there’s a high brick wall surmounted by broken glass and electric wiring surrounding the estate. The wiring is connected to an alarm system operated from inside the house.’
‘I see. The professor must have been very worried about the possibility of a break-in. Would you agree that the system would have cost a lot of money?’
‘Yes. I’d say so.’
‘And what about the main gate? How is that opened?’
‘It’s also operated electronically either from a unit beside the gate or by remote control from inside the house.’
‘Was the gate open or closed when police arrived?’
‘Officers Clayton and Watts were the first to attend. It’s my understanding that they found the gate closed.’
‘And what about the doors of the house itself?’
‘I entered through the main front door, which was half open when I arrived. All the other exit doors of the property were locked except for the French windows in the professor’s study, which were also partially open, and the door at the front of the west wing, which was closed but not locked.’
‘These French windows to the study. There are thick, floor-length curtains in front of them. Isn’t that right, Inspector?’
‘Yes. They were half drawn.’
‘And there would be space between the curtains and the doors for a person to hide if he wanted to?’
‘I suppose so.’
‘Making him invisible to a person inside the room.’
‘Yes.’
‘Thank you. Now Mr Thompson asked you some questions about my client’s interview …’
‘One moment, Mr Swift,’ interrupted the judge. ‘I’m sure you want the members of the jury to have a full picture of this security system. Isn’t that right?’
‘Yes, my lord.’
‘Well, perhaps the inspector can help us with whether there is any record of the alarm going off on the night of the murder.’
‘No record, my lord,’ said Trave.
‘And is there any forensic evidence of anyone breaking
