Plot Summary:

When a ghost hunter show comes to town, it’s up to Gethsemane and Eamon to solve the unexpected murder of the host, allowing the brand-new spirit to cross-over.

My Rating:

My Thoughts:

Gethsemane and Eamon are back with a new mystery this time at an Irish castle. It’s a very interesting movie. Will Gethsemane pick between Griff and Inspector O’Reilly?

I like how, in each installment, Gethsemane gets further into solving the mysteries that she ends up getting involved in. Eamon is getting better at helping out Gethsemane, even if he technically doesn’t have to come back to help her anymore.

The mystery is kind of weird. I didn’t really care for the victim, though. The host wasn’t a great person and is making it hard for Eamon and Gethsemane to solve the mystery so he can cross over.

For Gethsemane’s love interests, I have to say that I like her with Griff better than the inspector. I think the reason is that Griff and her have more chemistry.

Gethsemane and Eamon are great sleuths together, and I like watching them solve the mysteries. It’s funny when she is talking to him, and everyone pretends like they don’t know what she is doing. Gethsemane and Eamon both have their strengths that work well together when solving mysteries. Eamon can go places Gethsemane can’t. Tamera and Ristead make a great pair of sleuths, and their chemistry is good for friends.
