Books from the Backlog - A Beautiful Blue Death

Today I'm linking up with Carole from Carole's Random Life of Books for Books from the Backlog.  I really enjoy the chance to feature a book that's been hiding in the piles of books for far too long!

Goodreads:  A Beautiful Blue Death by Charles Finch

Blurb:  On any given day in London, all Charles Lenox, Victorian gentleman and armchair explorer, wants to do is relax in his private study with a cup of tea, a roaring fire and a good book. It's a nice life. But when his lifelong friend Lady Jane asks for his help, Lenox cannot resist another chance to unravel a mystery, even if it means trudging through the snow to her townhouse next door.
One of Jane's former servants, Prudence Smith, is dead -- an apparent suicide. But Lenox suspects something far more sinister: murder by a rare and deadly poison. The house where the girl worked is full of suspects and, though Prudence dabbled with the hearts of more than a few men, Lenox is baffled by an elusive lack of motive in the girl's death.

When another body turns up during the London season's most fashionable ball, Lenox must untangle a web of loyalties and animosities. Was it jealousy that killed Prudence? Or was it something else entirely different, something that Lenox alone can uncover before the killer strikes again?

Why It Needs to Come Off the Shelf:  I read and enjoyed this one back in 2018 but remember absolutely nothing about it.  I want to continue with the series but need to get this one read before I start the next one.
