The Comfort of Saturdays, by Alexander McCall Smith (Little, Brown, Ł17.99)

All the favourite characters are here in McCall Smith's latest novel set in genteel circles of Edinburgh.
Isabel Dalhousie, philosopher and editor of 'The Review of Applied Ethics', now finds herself experiencing a mixture of emotions- doubts, anxieties, guilt- as she adjusts to motherhood and her relationship with baby Charlie's father, the much younger, very attractive Jamie.
However, this does not prevent Isabel from entering once more into the fray when justice appears compromised. Is this altruism or interference in the lives of others?
The ethical questions raised engage and challenge the reader.
The comfort factor will warm winter nights!
