Trying to save an endangered species doesn’t normally target one for extinction. But homicide detective Hannah Sampson has her doubts when Elyse—her close friend and neighbor—dies from a fiery boat explosion. The local police believe she committed suicide. But Hannah knows that Elyse—a staunch environmentalist—was too dedicated to preserving life to take her own. But if Hannah is going to hook her friend’s killer, she’s going to have to chart her own course—and make sure that her deep sea forensics don’t get her in way over her head…

EDITORIAL REVIEWS

"Fast-paced thriller…that explodes onto the opening page. By the end of the first chapter, Brandt’s heroine is breathless and the reader is hooked."
--Diver Magazine

“A plunge into intrigue. Brandt is in her element as underwater sleuth.”
--The Denver Post

“White-hot writing, a charismatic heroine and crackling tension flawlessly merge in Brandt’s latest Underwater Investigation. Plus, her crisp depiction of the British Virgin Islands lends lush atmosphere to this suspenseful story. Police diver Hannah Sampson is smart, skillful and independent. But her independence makes things difficult when her best friend is seriously injured in a boat fire. Hannah’s the only person on the island who believes the fire was a murder attempt. Clues lead to dead ends, but
Hannah knows she’s onto something. Threats against her own life reinforce her gut instinct and push her toward a risky resolution.This richly plotted mystery is as satisfying as finding buried treasure.”
—Romantic Times Magazine

“Beginning in Swimming With the Dead, and then Dark Water Dive, Brandt introduced Hannah Sampson, an independent and spunky heroine who, not coincidentally, hails from Colorado. Her special talents, aside from a quick, sometimes raw wit and a bulldog-like curiosity,include diving. While the storylines in Brandt’s books are compelling and the plots, filled with murder, pending murder, and intrigue, keep the pages turning, it’s really her special gift for atmosphere that has kept me reading. Her latest book, Dangerous Depths, is no exception. I will say that Brandt continues to grow as a writer and her heroine, Hannah Sampson, emerges as a more fully developed and complex character. And, as much as I like Sampson, I enjoy the descriptions of the British Virgin Islands even more, particularly the detailed evocations of diving that can almost make you taste the regulator in your mouth.”
