In the eerie stillness of a moonlit night, a ravenkeeper is brutally murdered outside the Tower of London. The only potential witness, his daughter, missing . . .

Scotland Yard Inspector Henry Field has few clues to follow but is determined to prove his quick rise through the ranks of the Metropolitan Police wasn't simply because of his last name. Yet when the ravenkeeper's daughter is found, the case becomes even more complicated.

Discovering the frightened, disheveled girl on her doorstep is a shocking start to widow Amelia Greystone's day. So is the inspector assigned to the case—the same one who has yet to solve her husband's murder.

Soon the investigation takes a dangerous turn that rouses fear of the legend surrounding the Tower's ravens and threatens the Queen herself.

Can the unlikely pair protect the newly orphaned girl and halt the killer before he strikes again?
