Mrs. Malory: Death of a Dean (Mrs. Malory Mystery)

Sheila Malory's childhood friend has hit hard times, and is desperate enough to try selling the family mansion out from under his stubborn elderly nanny. Unfortunately, the estate can't be sold unless the old woman moves or expires. When she suddenly turns up dead and his much-hated brother is poisoned, Sheila's long-time companion becomes the primary suspect. But she soon finds that things aren't as simple as they look, and even those she trusts may have something to hide.
