Silence in the Library — Katharine Schellman

The second Lily Adler historical mystery is “a tale of 19th-century female empowerment . . .  a clever murder puzzle, [and] an immersion in a bygone era” (Kirkus Reviews).

Regency widow Lily Adler didn't expect to find a corpse when visiting a family friend . . .

Regency widow Lily Adler has finally settled into her new London life when her semi-estranged father arrives unexpectedly, intending to stay with her while he recovers from an illness. Hounded by his disapproval, Lily is drawn into spending time with Lady Wyatt, the new wife of an old family friend. Lily barely knows Lady Wyatt. But she and her husband, Sir Charles, seem as happy as any newly married couple until the morning Lily arrives to find the house in an uproar and Sir Charles dead.

All signs indicate that he tripped and struck his head late at night. But when Bow Street constable Simon Page is called to the scene, he suspects foul play. And it isn't long before Lily stumbles on evidence that Sir Charles was, indeed, murdered.

Mr. Page believes the surviving family members are hiding the key to Sir Charles' death. To uncover the truth, Lily must partner with Captain Jack Hartley -- and convince her father to help catch his friend's killer before anyone else in the Wyatt household dies.
