In this latest installment of the beloved Isabel Dalhousie series, everyone's favorite moral philosopher and amateur sleuth takes on a new set of delicate disputes

Isabel has an unwavering commitment to her principles, which means she is often asked to advise on the sensitive, personal affairs of others—even those whose business she would prefer to stay out of.

When Isabel receives a surprise visit from a friend who has recently discovered the existence of a long-lost brother, she will have to face this quandary in her usual deft and thoughtful way. The friend has always held her father in high regard, and is worried that knowledge of his affair will tarnish her siblings’ perception of him. Meanwhile, Isabel’s husband Jamie has been offered the gig of his dreams—the opportunity to play in a series of concerts at a prestigious venue in London. After meeting the series coordinator, it becomes clear to Isabel that the woman has a massive crush on Jamie. Isabel isn’t sure whether to reveal the woman's intentions. Should she tell Jamie of her suspicions, or would that mean calling his talent into question?

And finally, the ever-frustrating Professor Lettuce returns, this time embroiled in a ridiculous dispute with his friend Professor Dove. Somehow, Isabel gets dragged into resolving the affair. As always, Isabel will have to use her pragmatic sensibility and kindness to navigate these tricky situations.
