Billy, still looking down, shook his head. "No," he muttered, "no children. Deirdre wasn't keen."

"And what do you do? I mean, what do you work at?"

"Commercial traveler. Pharmaceuticals. The job takes me away a lot, around the country, abroad too-the odd occasion to Switzerland, when there's to be a meeting at head office. I suppose that was part of the trouble, me being away so much-that, and her not wanting kids." Here it comes, Quirke thought, the trouble. But Billy only said, "I suppose she was lonely. She never complained, though." He looked up at Quirke suddenly and as if challengingly. "She never complained-never!"

He went on talking about her then, what she was like, what she did. The haunted look in his face grew more intense, and his eyes darted this way and that with an odd, hindered urgency, as if he wanted them to light on something that kept on not being there. The waitress brought Quirke's tea. He drank it black, scalding his tongue. He produced his cigarette case. "So tell me," he said, "what was it you wanted to see me about?"

Once more Billy lowered those pale lashes and gazed at the sugar bowl. A mottled tide of color swelled upwards from his collar and slowly suffused his face to the hairline and beyond; he was, Quirke realized, blushing. He nodded mutely, sucking in a deep breath.

"I wanted to ask you a favor."

Quirke waited. The room was steadily filling with the lunchtime crowd and the noise had risen to a medleyed roar. Waitresses skimmed among the tables bearing brown trays piled with plates of food-sausage and mash, fish and chips, steaming mugs of tea and glasses of Orange Crush. Quirke offered the cigarette case open on his palm, and Billy took a cigarette, seeming hardly to notice what he was doing. Quirke's lighter clicked and flared. Billy hunched forward, holding the cigarette between his lips with fingers that shook. Then he leaned back on the banquette as if exhausted.
