The Devil's Eye

The Devil's Eye is the 4th book in the Alex Benedict series by Jack McDevitt. I always enjoy this author. I've read many books by him, and he never disappoints. I'm reading these in publication order, but it's not necessary in this series.

from the back of the book:

Alex Benedict, interstellar antiquities dealer, and his assistant, Chase Kolpath, are on vacation when they receive a cryptic message from celebrated writer Vicki Greene, whom neither has ever met, asking for help. But when they return home, Alex discovers that Greene has asked for and been given a mind wipe. She has no memory of her past life or of her plea for assistance. Yet she has transferred an enormous sum of money to Alex. But for what purpose?

To answer that question, Alex and Chase venture to the place where Greene had been vacationing prior to sending her message. It is the most remote of human worlds, literally outside the galaxy. There, they will uncover a secret connected to a decades-old political upheaval, a secret somebody is desperate to keep hidden -though the price of that silence is unimaginable...

SF Site calls it "satisying" and closes with this:

As with all of McDevitt's novels, it provides the reader's sense of wonder with numerous fantastic settings and situations. McDevitt's universe, while not exactly space opera, provides the feeling of that subgenre imparts to its readers while incorporating the science of hard science fiction, well-defined characters, and, in the case of The Devil's Eye, a mystery to be solved.

Eyrie.org has a positive review. SFF World concludes, "The Devil’s Eye was one of the more fun Science Fiction novels I read this year and I can’t help but give this one a high recommendation."
