Free Deception on His Mind by Elizabeth George

I was talking about. When people don't keep to their own, there's trouble. If one allows immigration from a culture with no respect for human life, then one can hardly quail before the prospect of representatives from that culture walking about with knives. Frankly, Theo, you were lucky the little heathens weren't carrying scimitars.”
    Theo got up abruptly. He walked to the sandwiches. He picked one up, then put it down. He settled his shoulders.
    “Gran, the English boys were the ones with the knives.”
    She recovered quickly enough to say tartly, “Then I hope you relieved them of them.”
    “I did. But that's not actually the point.”
    “Then kindly tell me what the point is, Theo.”
    “Things are heating up. It's not going to be pleasant. Balford-le-Nez is in for some trouble.”

INDING A SUITABLE ROUTE TO GET OUT TO ESSEX WAS a case of damned if you do and damned if you don't. Barbara faced the choice of crossing most of London and weaving her way through mind-numbing traffic or risking the vehicular uncertainties of the M25, which orbited the megalopolis and even at best of times required one to put all plans for a timely arrival at one's destination temporarily on hold. With either choice, she would get to sweat. For the coming of evening hadn't brought with it the slightest corresponding drop in temperature.
    She chose the M25. And after throwing her haversack into the back seat and grabbing a fresh bottle of Volvic, a packet of crisps, a peach, and a new supply of Players, she set off on her prescribed holiday. The fact that it wasn't a bonafide holiday didn't bother her in the least. She'd be able to say airily, “Oh, I've been to the sea, darling,” should anyone ask her how she'd spent her time away from New Scotland Yard.
    She drove into Balford-le-Nez and passed St. John's Church just as its tower bells were chiming eight o'clock. She found the seaside town little changed from what it had been during the annual summer holidays she'd spent there with her family and with her parents’ friends: the corpulent and odoriferous Mr. and Mrs. Jenkins—Bernie and Bette—who yearly followed the Haverses’ rust-spotted Vauxhall in their own compulsively polished Renault, all the way from their London neighbourhood in Acton east to the sea.
    The approach to Balford-le-Nez hadn't altered at all in the years since Barbara had last been there. The wheat fields of the Tendring Peninsula gave way on the north of the Balford Road to the Wade, a tidal marsh into which flowed both the Balford Channel and a narrowing estuary called the Twizzle. When the tide was in, the water of the Wade created islands out of hundreds of boggy excrescences. When the tide was out, what remained in its ebb were flats of mud and sand across which green algae stretched slimy arms. To the south of the Balford Road, small enclaves of houses still stood. Stucco-walled and squat, sparse of vegetation, these were some of the old summer cottages occupied by families who, like Barbara's own, came to escape the seasonal heat of London.
    This year, however, there was no escaping. The wind that blew in the Mini's window and ruffled Barbara's crop of ill-cut hair was nearly as hot as the wind she'd felt as she'd driven out of London a few hours earlier.
    At the junction of the Balford Road and the High Street, she braked and considered her options. She had nowhere to stay, so there was that to see to. Her stomach was rumbling, so there was food to dig up. She was in the dark as to what kind of investigation into the Pakistani man's death was actually in progress, so there was that to suss out as well.
    Unlike her superior officer, who never seemed to manage a decent meal, Barbara wasn't one to deny her stomach its due. Accordingly, she turned left down the gentle slope of the High Street beyond which she had her first glimpse of sea.
    As had been the case in her girlhood, there was no dearth of eating establishments in Balford, and most of them
