QUOTE : awake that she climbed out of bed and went to the window. She pulled the curtains aside, but the Kanes’ house was in darkness. She went back to bed, switched on her bedside lamp and picked up the crossword she had been trying to finish before she had grown too sleepy. One of down clues was ‘Together, the top and bottom of the world are manic’. The answer was ‘bipolar’. *** Next morning, as she came back with Barney from his early-morning walk, she found David Kane standing in her porch with the collar of his grey raincoat turned up. It was raining hard now and Barney had been stopping every few yards to shake himself. ‘Good morning, Katie,’ said David. ‘That’s the trouble with dogs, isn’it? You have to take them out to do the necessary, whatever the weather.’ Katie lowered her umbrella and shook it. ‘Don’t you have a dog?’ she asked him. ‘No, I couldn’t. If my patients smelled another dog in the house, whether they were dogs themselves or cats or whatever, they’d find it very disturbing.’ He stood close beside her as she unlocked her front door. ‘Talking of disturbing, the reason I’ve come over is to apologize for all the racket we were making last night, Sorcha and me. Sorcha was having one of her episodes.’ Katie stepped into the hallway and Barney followed her. David stayed in the porch as she hung up her raincoat. ‘Has she been back to her doctor?’ she said.
