About
In the pitch-black waters beyond a long-abandoned fishing town, the enigmatic captain of the world's strangest submarine has been murdered. Some say he was an immortal time-traveller. Others say he was a vampire, cursed to stay hidden beneath the waves forever...
Found alone in a locked room, with only an ancient stone cauldron to suggest how he might have died, it's up to Detective Grimoire and Sally to piece together what really happened. Was it a curse, released from the cauldron? One of the submarine's eccentric crew? Or does the bizarre truth run even deeper...
• Every clue is a fully realised 3D object waiting to be examined for hidden secrets
• Grimoire and Sally are back, and joined by a fully voiced cast of mysterious suspects
• A hauntingly beautiful original soundtrack performed by the Budapest Art Orchestra
• Explore every hand-painted inch of The Mortuga Submarine, where not all is as it seems...

Very good
Had a wonderful time playing this game. The voice acting was top notch and I was so engaged the whole time!
The art is so full of life and character, the music is catchy and moving, the plot is gripping, and the characters are unique and fun in their own ways. Instant recommend for point and click fans, vn fans, or mystery fans.
This was worth the wait. I think that this one is the best in the series so far
Another great point n click locked room murder mystery! Thoughtful dialog on every item you could want to click, kinda makes up for the fact you will probably have to click on everything and everyone and get everyone's opinion of everything and everyone. The game is very engrossing though, I was very excited to play it all the way through as soon as it came out.
Desde que jugué el primer juego de detective grimoire, se volvió uno de mis juegos favoritos de este genero, esta entrega no decepciona en nada, tiene una historia y personajes increíbles. Sin dudarlo vale cada centavo, es una saga increíble y ojala sigan haciendo juegos así de buenos
I'm only halfway through at time of review and already I have to say this may be one of the best detective games I've ever played (and I've played a lot!). Marvelous characters, an intriguing locked-room murder mystery, and lets you figure things out on your own with a minimum of hand-holding. Like the rest of the series, it makes you feel smart without making you feel dumb (if that makes sense).
