Mars At Twilight

 The final installment featuring Detective Ace Sloan

4 out of 5 stars

Multiple murders have been committed on Mars and the best Martian detective Ace Sloan is on the case.

Adam Schulmerich narrated Mars At Twilight and does a really nice job with it. His pacing and narration style worked well with the story, though I’m disappointed that all four books were narrated by different narrators.  I think that an overall narrator “playing” Detective Ace Sloan would make these stories blend together better. But, Schulmerich still does a good job narrating and I was not disappointed at all.

Mars At Twilight felt like it was the shortest of the entire series.  Graham weaves in a little more personal story into the detective mix but it still felt shorter than the other novellas in this series.  Even though it was short, it was still an enjoyable combination of old school detective and new school science fiction (though, this one was lacking on the sci-fi part a bit).

Overall, the final Ace Sloan story was a bit of a flop for me.  I still enjoyed it, and the story was a quick and easy one to follow, but it just left me feeling like there could have been more.  I’m not even upset with the ending (I’m trying hard not to spoil it for anyone).  I’ve come to enjoy Graham’s short fiction, but this one… just needed a little more.

I was given a copy of this book in exchange for my honest and unbiased opinion.  The original review can be seen on Audiobook Reviewer.

In this fourth and final installment of the Detective Ace Sloan series, Sloan must solve the murders of multiple members of a prominent Martian family and a distinguished poet all while cultivating a relationship with a new lover and dealing with a sudden serious health issue.

More than ever, he must lean on Detective Kate Hammer to assist him in solving the crimes. Like the other Sloan mysteries (The Red Planet Murders, The Red Planet President, and Mars at Midnight), this book brims with intrigue and suspense set against the Martian landscape in the 22nd century.
