Isabel Dalhousie thinks often of friends, sometimes of lovers, and on occasion of chocolate. As an Edinburgh philosopher she is certain of where she stands. She can review a book called In Praise of Sin with panache and conviction, but real life is...well, perhaps a bit more challenging - particularly when it comes to her feelings for Jamie, a younger man who should have married her niece, Cat.

When Cat takes a break in Italy, Isabel agrees to run her delicatessen. . . . . . . . . .
