Second paragraph of third chapter:
Surprise stopped Anne midway across the living room. Granted the room wasn’t huge, but a pair of two-seater sofas, separate miss-matched chairs, a coffee table, sideboard and bookcase, left plenty of room to walk between the furniture. A sense of Madeleine’s apology extending far beyond the limits of her home unsettled Anne, though she struggled to understand why. Before she could enquire, Madeleine pushed them into a whirlwind tour, cutting their greeting short.
Second in the Bloodlines sub-series of Lethbridge-Stewart books, in which Anne Travers and her husband Bill visit France to investigate sinister gangs-on and body-horror in a laboratory. The story is decently enough told, but the connection with Doctor Who so weak that I think I may clear this sequence from my reading list in future. You can get it here.
