After the interview, Banks felt the urge to get out of the station, away from the acrid stink of Norman Wells’s sweat, so he decided to head out Lyndgarth way and talk to Luke Armitage’s music teacher, Alastair Ford, while Annie continued to supervise the search for Luke’s mystery woman.

In Banks’s experience, music teachers were an odd lot indeed, partly, no doubt, because of the frustration of trying to instill the beauties of Beethoven and Bach into minds addled with Radiohead and Mercury Rev. Not that Banks had anything against pop music. In his day, the class had kept pestering their music teacher, Mr. Watson, to play The Beatles. He relented once, but looked glum the whole time. His feet didn’t tap, and his heart wasn’t in it. When he played Dvoák’s New World Symphony or Tchaikovsky’s Simphonie Pathétique, however, it was another matter. He closed his eyes, swayed and conducted, hummed along as the main themes swelled. All the time the kids in the class were laughing at him and reading comics under their desks, but he was oblivious, in a world of his own. One day Mr. Watson failed to turn up for class. Rumor had it that he’d suffered a nervous breakdown and was “resting” in a sanatorium. He never returned to teaching as far as Banks knew.

Yesterday’s rain had rinsed the landscape clean and brought out the bright greens of the lower daleside, dotted with purple clover, yellow buttercups and celandines. The limestone scar of Fremlington Edge glowed in the sunlight, and below it the village of Lyndgarth, with its small church and lopsided village green, like a handkerchief flapping in the wind, seemed asleep. Banks consulted his map, found the minor road he was looking for and turned right.

Ford’s cottage was about as isolated as Banks’s own, and when he parked behind the dark blue Honda, he understood why. It wasn’t the New World Symphony but the beautiful Recordare for soprano and mezzo-soprano from Verdi’s Requiem blasting out of the open windows at full volume. If Banks hadn’t been playing the Stones’s Aftermath CD in the car, he would have heard it a mile away.

It took a bit of hammering at the door, but eventually the music quietened down and it was answered by the man Banks recognized from the Aeolian String Quartet concert. Alastair Ford had five o’clock shadow, a long, hooked nose and a bright gleam in his eyes. If he had any, his hair would probably have been sticking out in all directions, but he was quite bald. What was it about Luke Armitage? Banks wondered. This was the second person he’d met that day who had spent time with the boy and looked as mad as a hatter. Maybe Luke attracted weirdos. Maybe it was because he was more than a little weird himself. However, Banks determined to keep an open mind. Whether Alastair Ford’s eccentricity had a dangerous edge remained to be seen.
