About The Secret Investigator of Astor Street

Piper Sail Mysteries Book 2

Piper Sail has a new mystery to solve—and a future to figure out.

Only a few months ago, eighteen-year-old Piper Sail was solving the mystery behind her best friend’s kidnapping. But with high school behind her, Piper isn’t sure what she’s meant to do next with her life—college holds no interest, and as much as she loves her detective boyfriend, she’s not ready to think about settling down. The one thing she wants is to become an investigator, but that simply isn’t done. Not when you’re a girl, and especially not one from a wealthy family.

When a student at her old school asks Piper to investigate her brother’s death, Piper secretly takes the case. Her determination to discover the truth leads her into the seedy underbelly of 1920s Chicago, where clue after clue indicates there’s more to the brother’s death than what the family has been told.

But shifts in her personal relationships and the case itself leave Piper doubting if she’s truly fit to be an investigator at all. As danger closes in, Piper will need all her wit and daring to uncover the truth—before she becomes the next victim.

Stories That Stay With Readers

Nadine Brandes, bestselling and award-winning author of Fawkes, Romanov, and The Nightmare Virus

“I would follow Piper anywhere—into speakeasies, smoky backrooms, or straight into danger. This is historical fiction at its most fun!”

Lorie Langdon, author of the Disney Happily Never After series

“A delightful whodunit mystery that will have you flying through the pages and wishing the indomitable Piper Sail could be your best friend. I loved everything about The Secret Investigator of Astor Street, from the 1920s setting to the sweet romance and the suspenseful anticipation Stephanie Morrill expertly builds with every chapter. A highly recommended read for all ages!”

From Booklist:

“Morrill produces a historical novel that blends devastating true events with lifelike fictional characters as it brings history to life.”
