'What about lights? What lights were on in the building?'
'When I arrived, none that I could see. But there wouldn't be. Mr. Potter's room looks out on the back.'
'How do you know that?' demanded Chivers. 'You told me you never got into his room, only as far as his secretary's office.'
'I didn't. But I know which way I'm facing.'
'Always?'
'Usually.'
'Not a Muslim, are you?'
'No. Why?'
'Could be a useful talent for a Muslim.'
Joe glanced towards the tape and coughed gently.
'Yeah, yeah. Well, thanks for your cooperation, Mr. Sixsmith. We may need to talk to you again and meanwhile if anything comes to mind that you think might help us, please get in touch. Interview ends at 20.15 hours.'
He switched the recorder off and sat glowering at Joe.
'You're a waste of my time and everyone's space, Sixsmith,' he said. 'Why don't you sod off out of here?'
'Hey, if you're going to get personal, let's have the recorder back on,' said Joe. 'Making jokes about Muslims just gets you killed, but being rude to witnesses may get you sued. What's your beef anyway, Sarge? I told you all I know. Don't want me making stuff up, do you?'
'No, don't want that,' said Chivers, relaxing a little. 'Just wanted a bit of a pointer but I suppose that was too much to hope for.'
Suddenly Joe got it. When Woodbine had been made up to superintendent, his detective inspector had become acting DC I, but Chivers hadn't moved up to acting inspector. Instead, a new young high flier had been appointed. But Scottish snow, African sun, and Asian flu had united to leave the sergeant temporarily in charge of the shop. A good quick result in a murder case would do him no harm at all and at the very least be a satisfying two fingers to his sceptical superiors.
He said, 'I'm doing my best, Sarge. You know that.'
He saw the man tremble on the brink of another insult then pull himself back, maybe recalling that Willie Woodbine had done OK by giving Joe his head.
'Yeah, sure,' he said. 'I meant it when I said, any little pointer.'
Happy to extend the phoney peace, Joe racked his brain for an idea.
There was the phone call,' he said. 'Someone called Felix. Listen, if you dialled 1471, you'd probably get his number
He saw from Chivers's face this was mutton to the Falklands.
'Felix Naysmith. One of the partners. Number was his holiday cottage in Lincolnshire. We rang back, but they must have gone out for the evening. No sweat. Unless Potter was actually attacked while he was on the phone, which doesn't seem likely, there's not much chance of Naysmith being able to help. It's those who were on the spot I'm interested in.'
Grinding his teeth significantly, Joe said, 'Like Ms lies, you mean?'
'Ms lies has been very helpful,' said Chivers, implying compared with some people. 'First off, she told us she heard a din upstairs and went to her door in time to see you flouncing out, yelling about killing lawyers.'
'I explained that.'
'Yeah, like you explained about forcing your way into the building, scaring the pants off the poor woman.'
'Come on, Sarge. Did she really say that?'
'No,' admitted Chivers reluctantly. 'Just the opposite. What she did say was that after you left she went back into her own room, leaving the door open so she'd see Potter when he came down. Fifteen minutes later when he hadn't shown and she was ready to leave, she rang his office. When he didn't reply she got worried.'
'Isn't there some other way out of the building?' interrupted Joe.
'How do you know that?' demanded Chivers, suspicion re-entering quick enough to show it hadn't retreated far.
'Because them houses were built for monied folk to live in with maids and cooks and backstairs and tradesmen's entrances,' said Joe.
That your deduction of the month, Sixsmith?' sneered Chivers. 'OK, there's still a backstairs and a rear entrance from the back yard. Takes you out into Ligover Lane.'
'So why was she worried when Potter could just have gone out the back way which, if his car wasn't parked out front, seems the most likely explanation?'
'She had a feeling something was wrong,' said Chivers.
'Sort of feminine intuition?' offered Joe.
'No. Sort of feeling anyone might get when an aggressive little black man bursts in, rushes upstairs, starts throwing furniture about, and storms out shouting stuff about killing people,' said Chivers.
'Yeah, well, we've been through all that, Sarge,' said Joe. 'So what's she do now?'
