The Sign of Four Spirits (Sherlock Holmes Bookshop Mystery Book # 9) by Vicki Delany

Gemma Doyle won’t be spooked when a body shows up at the psychic fair in bestselling author Vicki Delany’s ninth Sherlock Holmes Bookshop mystery.

When a psychic fair arrives in West London, Gemma Doyle, owner of the Sherlock Holmes Bookshop and Emporium, wants nothing to do with it. But somehow, at the urging of Donald Morris, an enthusiastic Sherlockian, she finds herself talked into attending a séance, along with baker and best friend Jayne Wilson, store assistant, Ashleigh, and former pop star Bunny Leigh.

But to her surprise, Gemma finds herself banned from the séance and shown the door. Curious, she listens in from outside the room. The medium informs a disappointed Donald that Sir Arthur Conan Doyle will not be able to make it tonight. Then, Gemma hears a voice cut off, a cry for help, a scream. Gemma bursts into the library to see that someone has collapsed on the table--dead. The windows are all locked, and Gemma was guarding the only door. Someone in this room is a murderer. But who?

The game is once again afoot for Gemma Doyle, as she hunts a killer. But, this time, is the killer of flesh and blood or had the medium summoned doom from beyond the veil?  (Summary via Goodreads)

I am a huge fan of Gemma Doyle and would love to be her best friend !!  She knows how to lead a fun life ... unfortunately she is not real.  Gemma Doyle is the main character in Vicki Delany's Sherlock Holmes Bookshop Mystery series.  This series is such an entertaining series to read and you cannot help but fall in love with Gemma and everything else within the books.

The Sign of Four Spirits is the ninth book in this series and Gemma and her best friend Jayne are roped into attending a seance by Gemma's employee, Ashleigh.  Ashleigh is going with her mother, Bunny, but wants reinforcements there to help.  Unfortunately Madame Lavalier has Gemma leave the room before starting because of Gemma's bad energy.  So Gemma being Gemma sits right outside the room so that she can hear as much as she can. 

Even though Gemma was not present when Madame Lavalier was murdered, she is able to help piece together some things for her boyfriend, Detective Ryan Ashburton and his partner Detective Louise Estrada.  Considering someone inside that room killed Madame Lavalier and then sat back down and acted like they didn't know or see anything takes a lot of guts !!  Unfortunately Gemma doesn't know most of the members that were at the seance so this case may be difficult for her, I mean the police, to solve.  

If there is one thing you know about Gemma is that she loves to solve cases and loves a challenge ... and this case will be a challenge .... especially when someone else from the group ends up dead also.

Readers will love this series and everything there is within the books.  You will love the characters, the shops, the town, and the murders and the way that Gemma can work through the cases.  She can walk into her shop, Sherlock Holmes Bookshop after having tea with Jayne at Mrs. Hudson's Tea Room and look around the store and know what was missing off the shelves and sold.  I highly encourage you to dive into this series if you haven't already started .....
