Mrs. Mohr Goes Missing by Maryla Szymiczkowa

Zofia Turbotyńska has been working on her husband's career for years but he's where she wanted him to be now.  So she decides to organize a charity raffle.  She goes to Helcel House, where elderly aristocratic ladies are being cared for by nuns.  She's surprised to find a woman missing.  She really wasn't well enough to go anywhere, so how could she be missing?

Houghton Mifflin Harcourt sent me an ARC of this book to read for review (thank you).  It will be published March 17th.

Zofia suggests they check the attic and when the watchman finds her body up thtere, he's shocked and frightened.  The police arrest him for the murder but Zofia doesn't think he was guilty.  After all, she had to point out to the police the lady was poisoned.  So then they arrest the cook.  She wasn't the killer either.  Then another woman at the home is strangled.  The cops have no idea who did it.  Neither does Zofia but now she begins her own investigative process.

She finds the ladies have come from a common background and connections no one knows about.  She also finds out one aristocrat is not who she claims to be.  As she begins tying all the loose ends together, the police tell her to get her nose out of the case.  She doesn't listen.  That's a good thing because they need her insight...
