Dragonfly in Amber by Diana Gabaldon

and tried to summon up that first conversation with the Randalls. "You have to be twenty-one to drink in Massachusetts," Claire had said. "Brianna still has eight months to go." Twenty, then. Brianna Randall was twenty.
    Unable to count backward fast enough, he rose and scrabbled through the perpetual calendar that the vicar had kept, in a clear space to itself on his cluttered wall. He found the date and stood with his finger pressed to the paper, blood draining from his face.
    Claire Randall had returned from her mysterious disappearance disheveled, malnourished, incoherent—and pregnant.
    In the fullness of time, Roger slept at last, but in consequence of his wakefulness, woke late and heavy-eyed, with an incipient headache, which neither a cold shower nor Fiona's chirpiness over breakfast did much to dispel.
    The feeling was so oppressive that he abandoned his work and left the house for a walk. Striding through a light rain, he found the fresh air improved his headache, but unfortunately cleared his mind enough to start thinking again about the implications of last night's discovery.
    Brianna didn't know. That was clear enough, from the way she spoke about her late father—or about the man she thought was her father, Frank Randall. And presumably Claire didn't mean her to know, or she would have told the girl herself. Unless this Scottish trip were meant to be a prelude to such a confession? The real father must have been a Scot; after all, Claire had disappeared—and reappeared—in Scotland. Was he still here?
    That was a staggering thought. Had Claire brought her daughter to Scotland in order to introduce her to her real father? Roger shook his head doubtfully. Bloody risky, a thing like that. Bound to be confusing to Brianna, and painful as hell to Claire herself. Scare the shoes and socks off the father, too. And the girl plainly was devoted to Frank Randall. What was she going to feel like, realizing that the man she'd loved and idolized all her life in fact had no blood ties to her at all?
    Roger felt bad for all concerned, including himself. He hadn't asked to have any part of this, and wished himself in the same state of blissful ignorance as yesterday. He liked Claire Randall, liked her very much, and he found the thought of her committing adultery distasteful. At the same time, he jeered at himself for his old-fashioned sentimentality. Who knew what her life with Frank Randall had been like? Perhaps she'd had good reason for going off with another man. But then why had she come back?
    Sweating and moody, Roger wandered back to the house. He shed his jacket in the hallway and went up to have a bath. Sometimes bathing helped to soothe him, and he felt much in need of soothing.
    He ran a hand along the row of hangers in his closet, groping for the fuzzy shoulder of his worn white toweling robe. Then, pausing for a moment, he reached instead far to the back of the closet, sweeping the hangers along the rod until he could grasp the one he wanted.
    He viewed the shabby old dressing gown with affection. The yellow silk of the background had faded to ochre, but the multicolored peacocks were bold as ever, spreading their tails with lordly insouciance, regarding the viewer with eyes like black beads. He brought the soft fabric to his nose and inhaled deeply, closing his eyes. The faint whiff of Borkum Riff and spilled whisky brought back the Reverend Wakefield as not even his father's wall of trivia could do.
    Many were the times he had smelled just that comforting aroma, with its upper note of Old Spice cologne, his face pressed against the smooth slickness of this silk, the Reverend's chubby arms wrapped protectively around him, promising him refuge. He had given the old man's other clothes to Oxfam, but somehow he couldn't bear to part with this.
    On impulse, he slipped the robe over his bare shoulders, mildly surprised at the light warmth of it, like the caress of fingers across his skin. He shifted his shoulders
