The Night the Penningtons Vanished — Marianna Heusler

Alone in her aunt's gift shop How Do I Love Thee? late one evening, Isabella Ripa opens the door to a glamorous woman carrying a birdcage. Isabella is enchanted by the woman's love birds and agrees to take them - at least for the night - until she can persuade her Aunt Talullah to adopt the pair, called the Penningtons. But in the morning the birds are gone. In their place is a book of love poems. As Isabella and her friends set out to recover the birds, they become embroiled in a mystery of a missing actress, a robbery and an intruder in Aunt Talullah's house.

The Night the Penningtons Vanished introduces a delightful trio of friends who work together to solve one strange problem after another. Buffetted by the demands of her teen years and conflict with her older sister, Isabella is determined to get to the bottom of the Penningtons mystery.
