Ambrose Lavendale, Diplomat

In Short

Ambrose Lavendale, Diplomat follows the adventures of Ambrose Lavendale and his astute partner, Suzanne de Freyne, as they navigate high-stakes espionage during the First World War. Moving between London hotels, coastal villages, and clandestine meetings, the pair uncovers dangerous formulas, exposes enemy agents, and thwarts complex German plots. Blending suspense, romance, and unexpected wit, E. Phillips Oppenheim crafts a gripping episodic tale of intelligence work where patriotism demands absolute sacrifice, ultimately culminating in a clever domestic ruse orchestrated by their friends.

The Story

The narrative begins in a bustling London bar where the looming threat of modern warfare hangs heavy, specifically the deployment of poisonous gases. Ambrose Lavendale encounters a shabby, unkempt inventor named Mr. Hurn, whose dangerous new creation attracts both legitimate interest and sinister attention. Alongside his companion Merrill, Lavendale takes Hurn to a secret demonstration, crossing paths with Suzanne de Freyne, a sharp-eyed woman who quickly becomes Lavendale's indispensable partner in clandestine investigations.

As the wartime crisis deepens, Lavendale and Suzanne track various nefarious actors across England and the Channel. They investigate a mysterious flat linked to Hurn's invention, encounter international financiers like Jacob P. Weald and Baron Cyril Ossendorf discussing munitions, and unmask a Japanese embassy attaché acting as a spy. Suzanne's unwavering dedication to France drives her forward, even when it requires cold calculation and the willingness to contemplate lethal intervention against enemy operatives. Their path involves relentless encounters with distinct personalities, including the smooth-talking German-American financier Mr. Kessner and former criminologist-turned-detective Mr. Courlander.

The investigation intensifies when General Matravers is threatened by a foreign imposter posing as a French envoy. Suzanne orchestrates a rapid dash across the English Channel aboard a British destroyer to reach the ailing general, leading them straight to a confrontation at Ranelagh. Following this lead, Lavendale and Suzanne trace stolen documents and secret correspondence to remote coastal locations like Blakeney, where they intercept important letters intended for enemy hands. Throughout these travels, the line between personal trust and patriotic duty blurs. Suzanne insists that true operatives must cast aside conventional character for the sake of their homeland, opening private letters and confronting suspects without hesitation.

The espionage network leads them into theatrical circles as well. Lavendale tracks down a celebrated Parisian actress known as Madame Félanie, unmasking her real identity as Adèle Goetz, an operative intertwined with a shady handler named Anders. By exerting quiet pressure and issuing stern ultimatums, Lavendale forces the spies to abandon England for America, securing stolen plans and protecting Allied secrets.

The journey finally winds down at a luxurious country estate hosted by Anthony Silburn. Here, amidst an atmosphere of aristocratic comfort and surreal gentility, Lavendale and Suzanne discover that their entire network of recent trials has been shaped by a playful yet elaborate practical joke orchestrated by their well-to-do peers. Rather than a tragic betrayal, the climax reveals a cheerful conspiracy designed to secure their union. The narrative resolves with a lighthearted marriage decree, uniting the two veteran investigators in a future free from secret service perils.
