Submersed Wonder, obsession, and murder in the world of amateur submarines

Matthew Gavin Frank

Book - 2025

"An exquisite, lyrical foray into the world of deep-sea divers, the obsession and madness that oceans inspire in us, and the story of submarine inventor Peter Madsen's murder of journalist Kim Wall-a captivating blend of literary prose, science writing, and true crime Submersed begins with an investigation into the beguiling subculture of DIY submersible obsessives: men and women-but mostly men-who are so compelled to sink into the deep sea that they become amateur backyard submarine-builders. Should they succeed in fashioning a craft in their garage or driveway and set sail, they do so at great personal risk-as the 2023 fatal implosion of Stockton Rush's much more highly funded submarine, Titan, proved to the world. Matthew ...Gavin Frank explores the origins of the human compulsion to sink to depth, from the diving bells of Aristotle and Alexander the Great to the Confederate H. L. Hunley, which became the first submersible to sink an enemy warship before itself being sunk during the Civil War. The deeper he plunges, however, the more the obsession seems to dovetail with more threatening traits. Following the grisly murder of journalist Kim Wall at the hands of eccentric entrepreneur Peter Madsen aboard his DIY midget submarine, Frank finds himself reckoning with obsession's darkest extremes. Weaving together elements of true crime, the strange history of the submarine, the mythology of the deep sea, and the physical and mental side effects of sinking to great depth, Frank attempts to get to the bottom of this niche compulsion to chase the extreme in our planet's bodies of water and in our own bodies. What he comes to discover, and interrogate, are the odd and unexpected overlaps between the unquenchable human desire to descend into deep water, and a penchant for unspeakable violence"--

Review by Booklist Review

As noted in his introduction to this scintillating investigative work, Frank did not intend to report on a true crime story when he began researching the worldwide personal submersible community. But the murder of journalist Kim Wall in a small submarine by a longtime member of that informal group could not be ignored, and so he threads the story of her efforts to cover the competition between Danish inventors into a larger tale about the allure of pushing the limits on underwater engineering and adventure. The media turned Wall's death into a sensation, but Frank's thoughtful approach resists the temptation to revel in lurid details. Instead, he delves into the intriguing history of submarines and how the lack of personal submersible regulation results in catastrophes like the implosion of the Titan submersible near the Titanic wreck site. He chronicles the misogyny and sexual harassment within the U.S. Navy submarine force, shares interviews with the almost entirely male fraternity of hobbyist fantasists and builders, and always returns to a faithful documentation of how Wall's dreams of a freelance opportunity brought her into the orbit of a psychopathic killer. Excellent for book groups, Frank's unique approach is a distinguished tour de force.

Review by Library Journal Review

The largely unexplored underwater world can be compared to outer space, with their enthusiasts finding similar thrills in seeing what no human has ever seen before. Journalist and poet Frank (Flight of the Diamond Smugglers) takes readers into the world of deep-sea diving, discussing the mythology, the history, and the personal submersibles (or PSUBS) community, all placed in the context of a murder committed by a submarine fanatic aboard his DIY vessel. The book starts with Peter Madsen's murder of journalist Kim Wall in Denmark's K'ge Bay in 2017. Frank then turns to the history of submarines, as far back as Alexander the Great, and finally to the contemporary community of amateur PSUBS builders and enthusiasts, which he says is marked by misogyny. Over the course of interviews with the hobbyists and even a dive on one PSUBS builder's vessel, Frank interrogates the risks this group takes in their quests to reach the extreme ends of the universe. VERDICT A well-documented look at the submarine community that combines true crime with science writing and history. It's a good pick for fans of Erik Larsen, as Frank also intersperses the events of a crime within a subject's larger context, all in engaging and haunting writing.--Maria Ashton-Stebbings

Review by Kirkus Book Review

Close encounters with DIY submarine culture's underbelly. A sharp researcher and stylish writer who's "obsessed with obsessives," Frank sets aside his lifelong fear of the ocean in this excellent book to plumb the peculiar depths of the DIY sub community. The water is cold. Beneath the niche fixations of geeky tinkerers and misfit enthusiasts, Frank discovers a strong undercurrent of violence and misogyny. The manosphere, it seems, has entered the bathysphere. "For some men," he writes, "the presence of a woman on the submarine not only conjures their inadequacies, but also reminds them that the sub itself...isn't so different from land: rife with whimsy, chance, perplexity." One such man would appear to be Peter Madsen. Convicted of the brutal 2017 killing in Denmark of Swedish freelance journalist Kim Wall, Madsen was a narcissistic amateur rocket builder who became obsessed with submarines as a "safe haven from surface mores," where he alone could exert "ultimate control." The story of the murder and its aftermath--including a prison sit-down between Frank and Madsen--provides a chilling throughline to an otherwise interdisciplinary look at what lies beneath the human compulsion to dive. Frank is witty and incisive--a sub-builder meetup, for example, is like being "trapped in a bouillon cube of white male machismo"--and he draws wonderful connections throughout. Along with contemporary academics, we encounter Aristotle, who was obsessed with the "watery world," and his student Alexander the Great, whose diving bell served as both tactical advantage and personal retreat. Mythic creatures of Nordic and Norse folktales arrive, as does Jules Verne, who we learn would find it absurd to dream of going 20,000 leagues deep (it was a measure of distance). We also spend time with a few amateur sub builders. The most memorable is Shanee Stopnitzki, "one of the few 'non-dudes'" in the community. She gives the book some of its best lines, including this one: "I think curiosity makes everything better." In this book, Frank's certainly has. A fascinating voyage among the hidden tides shaping a social niche. Copyright (c) Kirkus Reviews, used with permission.
