Submersed: Wonder, Obsession, and Murder in the World of Amateur Submarines

by Matthew Gavin Frank Narrated by Mark Deakins

Overview

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

"[A] thrilling study of an obsession-to sink below the surface, to depths both metaphoric and in fact. Full of wild characters and strange histories, by the end we are convinced, in no small part by the beauty of [Frank's] language, that this is one of the most important stories ever told."-Nick Flynn, author of This Is the Night Our House Will Catch Fire

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.

Editorial Reviews

From the Publisher

Frank, an accomplished author of narrative nonfiction, uses his terror as inspiration for this exploration of personal submersibles. . . . Frank’s painstaking research . . . yields evocative mini-portraits, whatever his subject. . . . The sheer depth of Frank’s skill [means] we can smell the damp wood and tequila in the Alaskan cabin where one Nazi-obsessed submariner builds his vessels. . . . His book . . . conjure[s] so vividly Wall’s character and the tragedy of her death.”
—Peter Sagal, The New York Times Book Review

“Matthew Gavin Frank dives into the subculture of DIY submersible enthusiasts. . . . Frank hopscotches across the globe, from British Columbia to Alaska to Denmark, to interview a colorful cast about their calling. . . . Frank questions his penchant for being ‘obsessed with obsessives,’ but zealots are kind of his thing. . . . It would be spoiling the story to reveal what his [own deep-sea dive] was like — just know that he journeys 2,000 feet under the sea, and lives to write the story.”
—Shelia McClear, The Washington Post

“A fascinating mash of crime narrative, psychological profiling and a peek inside the same misogynistic, all-consuming inventor culture that led to the Titan submersible implosion.”

“A cut-above true crime tome. . . . Frank’s hybrid work defies genre as masterfully as it confronts the dark allure of the deep. . . . Frank’s language is stunning—lyrical without losing clarity, philosophical without becoming murky. This book reads like deep-sea pressure: it builds slowly and then refuses to let go. . . . Mesmerizing. . . . [A] literary triumph.”

"Submersed might be the scariest book I’ve ever read: I can feel little bubbles of panic float up in me if I just imagine stepping onto an amateur submarine. But I’ll follow an essayist like Matthew Gavin Frank anywhere, and he’s crafted an exceptional journey into the down deep, beautifully examining 'the nagging drive to embed the body into a balloon-like enclosure and float alongside the fishes.' Reading this book, I felt rearranged at an atomic level. What a gift."
—Kristen Radtke, author of Seek You: A Journey Through American Loneliness

“Submersed is a dizzying and riveting descent into obsession, toxic masculinity, and the irresistible desire to reach new depths or tell a good story. Matthew Gavin Frank plunges far beneath the surface to observe the best and worst of humanity. A work of narrative nonfiction that is as astonishing as diaphanous sea creatures. One of the best books I've ever read."

"Matthew Gavin Frank is a master storyteller. A poetic true-crime cousin of Truman Capote’s classic In Cold Blood, Submersed navigates the horrific murder of journalist Kim Wall, the eccentric culture of the DIY submersible community, and our human relationship to large bodies of water. Believe me, you won’t be able to put this book down until you arrive at the very last page. It’s stunning, commanding, and haunting all at once."
—S. Kirk Walsh, nationally bestselling author of The Elephant of Belfast

"From the DIY pop-up postindustrial steampunk shipyards of Denmark to misogyny and murder, Matthew Gavin Frank is a furnace of intelligence and curiosity. Plumbing the depths and heights of the sea and the human condition, Submersed is an environmental story about obsession and desire, including Frank’s own, where he becomes embedded in the oceanic kelp of cultural complexities and complicated lives. Radiant, dark, elegant, perceptive, Submersed reveals how external landscapes affect our internal ones."
—Kerri Arsenault, author of Mill Town

“Scintillating. . . . 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. . . . Excellent for book groups, Frank’s unique approach is a distinguished tour de force.”
—Colleen Mondor, Booklist (starred review)

“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.”

“[An] aquatic escape. . . . Frank is afraid of the ocean, but that doesn’t stop him from diving into the water to learn about the murky world of DIY submarines.”

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.
