Capital

morning. Mill spoke to a Ghanaian and four Nigerians, none of whom gave any sign of knowing anything about Pepys Road or We Want What You Have. They were variously wary, sullen, and blank, but none of them, to his eyes, looked guilty, there were no clues and no tells. In Pepys Road itself he tried to interview a Kosovan warden who seemed not to speak any English at all, and barely to understand any either. Gradually this whole idea came to seem like a stupid mistake, a notion from another world – the fact that these people were so cut off from the area they worked in was part of the problem, rather than the key to the mystery.
    There were four names outstanding on the list. One of the names was an -ic, which presumably meant another Kosovan. All of the other names were African. By about two o’clock, Mill had convinced himself that the idea of talking to traffic wardens was a dud; but he couldn’t stop, since he couldn’t write up the report in a convincingly arse-covering way until he’d spoken to every relevant warden. Then he could stick it in the file and forget about it. That, in this context, would be a result. Mill went into a sandwich bar on the high street, realised that it was more expensive and pretentious than he was in the mood for, but couldn’t be bothered to abandon his place in the queue and go and find another one. He ended up with gouda and prosciutto and rocket on ciabatta, and a two-quid bottle of sparkling mineral water, which would make him burp during his afternoon’s legwork, but the bubbles at least gave the illusion that you were drinking something more interesting. Sitting at a window seat with his five-quid sandwich, leaning carefully forward as he ate so as not to get food on his suit, Mill got out his notebook and checked the names and addresses. Three of them were local, the fourth, incredibly boringly, was in Croydon. He’d start with the nearest, a twenty-minute walk or so. Take advantage of the fact that it was one of the summer’s few rainless days.
    Actually it was a good sandwich. Mill didn’t mind paying for things as long as he felt he was getting what he paid for. He wiped his mouth with a napkin and set out down the high street, along the stretch by the side of the Common where a crew of street robbers on bicycles were currently targeting anyone on a mobile phone. Mill had been working on that project until he was pulled off it to do this. The street robbers came from the estate a few streets away, and had all the rat-runs and pavements down pat, so they weren’t an easy target, but the crew had slowed down in the long summer evenings.
    A small cluster of school-age teenagers were hanging about by the fishing pond. Term hadn’t finished yet, so they shouldn’t be there. Mill clocked them but his day was already sufficiently pointless without wasting time hassling chav truants – anyway that was a job for uniform. Ah, the uniform. How he didn’t miss it.
    He had underestimated the length of the walk – by the time he got to Balham it had been about half an hour and his feet were starting to hurt. Well, at least he’d feel virtuously exercised after his wasted day. He checked the notebook, found the house, rang the buzzer for the second floor. A thick, wary male African accent came over the intercom:
    ‘Yes.’
    ‘Kwama Lyons?’
    The pause was longer than it should have been and Mill immediately felt more alert.
    ‘Yes?’
    People who can immediately recognise a policeman are usually people who have reasons for immediately recognising a policeman. From its tone, the voice at the other end of the intercom had reasons for not wanting to talk to him.
    ‘I’m Detective Inspector Mill. I’m looking for a Kwama Lyons, for a routine inquiry.’
    ‘She is not here.’
    ‘But this is her home address?’
    ‘Her home address.’
    ‘Would you like to check my identification before we go on?’
    Legally, the man at the other end of the intercom was not obliged to let Mill into the house – a fact he perhaps knew. He must also know that acting odd would only make Mill more interested. So there was a pause now, during which Mill could hear the man weighing the choice. After about ten seconds he said,
    ‘I will come down.’
    Weighty footsteps approached down the stairs. A heavy-set African man in his thirties, his eyes rimmed with red, opened the door wearing, of all things, a grey cardigan. Mill put his foot over the threshold, good copper’s trick, and
