An engaging tale of some little-known Navy cryptology efforts before World War II.
A lightly fictionalized debut work focuses on pioneering codebreakers in the United States Navy in the years leading up to the Pearl Harbor attack.
Retired radio intelligence officer Zullo combines years of technical expertise with a passion for his subject to craft the first of two volumes about a group of 20th-century Navy cryptologists. Called the On-the-Roof Gang because classes were held on the roof of a Navy building, the effort involved 176 men trained between 1928 and 1941. The radio operators learned techniques of transmission analysis involving Japanese katakana telegraphic code in order to intercept Imperial Japanese navy communications. The key figure in the narrative is Petty Officer Harry Kidder, who in June 1924 is a Morse code expert and Navy radioman in the Philippines. An eager and enthusiastic ham radio amateur, Harry discovers puzzling extra letters in transmissions while pursuing his hobby. Determined to decipher what he has noticed, Harry finds out from a Navy memo that the letters are part of the Japanese katakana alphabet. He then asks a friend’s Japanese wife for assistance. She helps Harry develop a “symbol, sound, and letter chart.” Several months later, Harry, now back in the U.S., meets Lt. Laurance Safford, a radio communications officer in Washington, D.C., assigned to look into Harry’s claims. Alongside the two men is the brilliant Agnes Meyer, working as a civilian in Navy communications, who comes up with the idea to establish a training program, and the On-the-Roof Gang is born. The tale proceeds chronologically, discussing developments in code-breaking techniques during the 1930s as well as military history. Other chapters delve into Harry’s personal life and problems, including an incident in Hawaii that leads to his forced retirement before Safford works to fully reinstate him to the “Research Desk” in 1940.
The intriguing story picks up speed and tension toward the end, as Safford and Navy radio operators search for elusive “Winds Execute” messages that will provide evidence that shows what by then seems inevitable: “War with Japan was imminent and that the Japanese were likely to attack without warning.” While technically historical fiction due to the invented dialogue and scenes, Zullo’s book leans heavily toward nonfiction and will primarily appeal to readers interested in military history, code-breaking, and the war in the Pacific. The narrative sparkles with authenticity and is well organized and clear, enhanced by the judicious use of historical photographs and maps. But the inclusion of each of the 25 training classes tends to slow the dramatic pace. And while the fictional scenes are well crafted, Harry, Safford, and others remain primarily historical figures. Still, history buffs will appreciate the illuminating chronicle, which has been informed by archival sources, first-person accounts, and interviews with veterans. While some details could have been omitted to achieve a tighter story, the author’s firm grasp of events makes for a compelling read. Volume 2 promises to bring readers into the war. Kidder, affectionately known as Pappy, died in 1963 and was inducted into the National Security Agency’s Cryptologic Hall of Honor in 2019.

BOOK REVIEW
An affecting portrait of a prickly woman.
A lifetime’s worth of letters combine to portray a singular character.
Sybil Van Antwerp, a cantankerous but exceedingly well-mannered septuagenarian, is the titular correspondent in Evans’ debut novel. Sybil has retired from a beloved job as chief clerk to a judge with whom she had previously been in private legal practice. She is the divorced mother of two living adult children and one who died when he was 8. She is a reader of novels, a gardener, and a keen observer of human nature. But the most distinguishing thing about Sybil is her lifelong practice of letter writing. As advancing vision problems threaten Sybil’s carefully constructed way of life—in which letters take the place of personal contact and engagement—she must reckon with unaddressed issues from her past that threaten the house of cards (letters, really) she has built around herself. Sybil’s relationships are gradually revealed in the series of letters sent to and received from, among others, her brother, sister-in-law, children, former work associates, and, intriguingly, literary icons including Joan Didion and Larry McMurtry. Perhaps most affecting is the series of missives Sybil writes but never mails to a shadowy figure from her past. Thoughtful musings on the value and immortal quality of letters and the written word populate one of Sybil’s notes to a young correspondent while other messages are laugh-out-loud funny, tinged with her characteristic blunt tartness. Evans has created a brusque and quirky yet endearing main character with no shortage of opinions and advice for others but who fails to excavate the knotty difficulties of her own life. As Sybil grows into a delayed self-awareness, her letters serve as a chronicle of fitful growth.

A debut novel with bright spots, but unbalanced and lacking in finesse.
A high school senior pursues an affair with her teacher.
Seventeen-year-old Waldo, the narrator of McCurdy’s fiction debut, lives in Anchorage, Alaska, with her mother, though she’s long been the parent in their relationship. She heats her own frozen meals and pays the bills on time while her mom chases man after man and makes well-meaning promises she never keeps. Waldo blows her Victoria’s Secret wages on online shopping sprees and binges on junk food, inevitably crashing after the fleeting highs of her indulgences. Mr. Korgy, her creative writing teacher, has “thinning hair and nose pores”; he’s 40 years old and married with a child. Nevertheless—or possibly as a result?—Waldo’s attraction to him is “instant. So sudden it’s alarming. So palpable it’s confusing.” Mr. Korgy professes to want to keep their friendship aboveboard, but after a sexual encounter at the school’s winter formal that she initiates, an affair begins. Will this reckless pursuit be the one that actually satisfies Waldo, and is she as mature as she thinks she is? Waldo is a keen observer of people and provides sharp commentary on the punishing work of female beauty. Readers of McCurdy’s bestselling memoir, I’m Glad My Mom Died (2022), will surely be curious about the tumultuous mother-daughter relationship, and it is one of the novel’s highlights, full of realistic pity and anger and need. (“I want to scream at her. I want her to hug me.”) Unfortunately, the prose is often unwieldy and sometimes downright cringeworthy: When Waldo tells Mr. Korgy she loves him, “The words hang in the air in that constipated way they do when you know that you shouldn’t have said them.” Waldo frequently lists emotions and adjectives in triplicate, and events that could be significant aren’t sufficiently explored or given enough space to breathe before the novel races on to the next thing.
