Vanished, by Joseph Finder. Unabridged audio.
I have read and enjoyed many of Joseph Finder's novels, especially those set in the world of high finance.
Vanished starts a series with a new protagonist, Nick Heller. Heller is a former Special Services operative, now working as an upscale private detective. He is estranged from his father, in prison for financial fraud, and from his brother Roger, a high-level executive at a defense contractor.
One night in Washington, Roger and his wife Lauren are attacked. While Lauren lies in a coma, and Roger can't be located, their son Gabe calls Uncle Nick for help. What Nick Heller uncovers is a web of lies and conspiracy that may involve his employer, and maybe members of his own family.
The only thing I didn't totally but in this novel was the villain's plot to take over a publicly-held company. That is the sort of thing that the SEC would notice, but that is probably my background in finance that noticed that. That minor thing aside, I enjoyed the adventure, the characters, and the story.
The audio program for this novel was excellent. Holter Graham did much more than than just read the novel, he was truly a "voice actor" in his performance, especially how he voiced the teenage son Gabe.
The next Nick Heller novel is out, and I will pick it up soon.
