Beresfords take over the International Detective Agency

Beresfords take over the International Detective Agency when Mr. Carter gives Tommy Beresford a covert six-month leave to revive a failing business under the name of its absent manager, Theodore Blunt. The arrangement creates a working stage for Tommy and Tuppence Beresford’s partnership: an empty office, an invented professional identity, and a succession of cases in which detective fiction becomes both their training manual and their comic repertoire.

The Agency and Its New Managers

The International Detective Agency has been bought cheaply after nearing collapse. Mr. Carter proposes that it be restarted on a six-month trial, with Tommy as its manager. Theodore Blunt cannot fill the role: Scotland Yard has intervened over his indiscretions, and he is being detained while refusing to disclose everything the authorities want to know. Tommy’s employment is therefore not a conventional appointment but a discreet arrangement. Mr. Carter recommends that he take six months’ leave on grounds of ill health and says that running the agency under Blunt’s name will be outside his official concern.

The proposal also makes room for Tuppence. Mr. Carter suggests that the experiment may amuse Mrs. Tommy by giving her a chance to try detective work, and Tommy accepts that she will be part of the venture. A few days later, the Beresfords take possession of the agency’s offices on the second floor of a dilapidated Bloomsbury building. The grand claims painted on the sign—confidential agents, discretion, free consultations—contrast with the modest, improvised business behind them.

The office is arranged to make the new identity look plausible. Albert gives up his former role as a Long Island butler and becomes an office boy, playing the part with inky hands, a tousled head, and a paper bag of sweets. Two doors divide the inner rooms: one marked for clerks and another for private business. Behind the latter, Tommy sits at a large desk among carefully labelled but empty files, leather-seated chairs, and a telephone. Tuppence works in the adjoining room with a typewriter and a gas ring for making tea. The setup is ready for clients; at first, clients are the one thing it lacks.

Learning the Profession by Playing It

Tommy recognizes that the couple are amateurs and tries to turn that disadvantage into a course of study. He fills the cupboard with detective stories by celebrated writers, intending to spend half-hours with the “Great Masters,” compare their methods, and acquire something like professional technique. When a chair gives way as he arranges the books, the high-minded programme begins in slapstick. Yet the books are more than decoration: Tommy treats detective fiction as a practical archive of styles, while Tuppence tests the gap between those imagined methods and the demands of real cases.

Their discussions make that gap explicit. Tuppence points out that Tommy lacks the medical, legal, and scientific qualifications associated with certain fictional investigators. Tommy answers by buying a camera and proposing to photograph footprints and enlarge the negatives. He reaches for the language of deductive mastery even as the evidence of his inexperience remains in view. The agency’s early method is thus neither purely professional nor purely fanciful: it combines observation and practical improvisation with borrowed detective roles.

That borrowing becomes a shared game whenever danger or uncertainty calls for a new approach. When Tuppence suspects that criminals have discovered Tommy is not the real Mr. Blunt, Tommy chooses the identities of the Okewood brothers, declaring himself Desmond; Tuppence prefers to play Francis, whom she considers the more intelligent sibling and the one who arrives in time to rescue his brother. Later, confronted with a fireman’s kit, she prompts Tommy to think through its purpose by invoking his “little grey cells” and Sherlock Holmes. Their exchanges turn literary allusion into a way of assigning roles, prompting deductions, and keeping their partnership nimble under pressure.

Disguise, Deception, and the Work of Detection

The cases teach the Beresfords to treat appearance as evidence that must be tested rather than trusted. In one episode, a door seems to have been locked from the other side; Elise catches up a towel, tries the handle again, and the door opens easily. The apparent obstruction proves transient, and the bedroom is empty. Such moments place the agency’s work at the uncertain border between what a scene seems to show and what its details actually establish.

The threat can also wear the appearance of official authority. Tommy is securely bound and gagged by a man who had presented himself as Inspector Dymchurch. Once the disguise drops, the supposed English inspector is revealed as a well-educated foreigner who speaks English without an accent. The change in voice and identity makes the danger plain: a title and an assured manner can be instruments of deception, not proof of legitimacy. Tommy’s assumed identity as Blunt puts him on the other side of the same problem, requiring him to perform a role convincingly while recognizing that others may be performing theirs.

The agency also confronts an attempt to draw Tommy away from its premises. An adversary wants him at the office at eleven that night, having used a famous “Blue” letter to lure him to Hampstead; the real aim is to enter the empty building and search the rooms. The plan depends on a mistaken assumption about the letter: a criminal who believes Tommy to be a genuine buyer of the business may expect it to have been filed as ordinary agency correspondence. The office, which began as a theatrical setting for the Beresfords’ invented profession, becomes a target precisely because that profession has acquired a convincing paper trail.

The Cases as a Shared Performance

The Beresfords’ role-playing is not confined to the agency’s furniture or name. Tommy explains a drug-smuggling plot by reversing the apparent importance of a diplomatic-bag switch. The question is not why someone wanted the Ambassador’s bag for an hour, but why someone needed the other bag to be in the Ambassador’s possession for that same interval. Because diplomatic luggage avoids a Customs examination, the exchange creates an opportunity to smuggle something compact; Tommy suspects drugs. He connects that logic to the performance staged in his office: the attackers had seen his advertisement and tried either to misdirect him or remove him from the way. A woman’s expression of blank dismay during Albert’s lasso act did not fit the part she was supposed to be playing, while the stranger’s attack was intended to make Tommy trust her. Tommy responds by performing credulity, allowing the woman to lure him away while leaving instructions behind and delaying their arrival so that help has time to act.

Even when the threat grows more personal, the couple fall back on the same repertoire. Tommy dramatizes the return of a supposedly defeated super-criminal by recasting him as No. 16, “4 squared,” and takes the role of Hercule Poirot; Tuppence answers by recognizing the performance. The joke does not make the danger unreal. It shows how the Beresfords use familiar detective-story conventions to frame an unfamiliar crisis and preserve their shared footing within it.

That reliance on appearances reaches its most painful consequence when Tommy discovers a bundle concealed under a sofa. Tuppence’s long black coat wraps her walking dress and hat, along with a long fair beard. The clothes expose a substitution: the supposed nurse and boy were accomplices, and the criminal had used prepared clothing and disguise to leave with Tuppence dressed as a boy. Mr. Carter identifies a fragment of a hypodermic needle on the carpet, establishing that she was drugged. The discovery shows the limit of performance as protection: disguises can help the Beresfords penetrate a scheme, but the same techniques can also conceal an abduction from them.

Significance

The takeover gives the Beresfords a recurring base from which to make detective work both a livelihood and a joint experiment. Its empty files, borrowed manager’s name, improvised staff, and tea-making gas ring keep the business visibly provisional, even as its cases demand increasingly consequential judgments. The contrast is central to the agency’s character: Tommy and Tuppence have no settled professional routine, so they adapt by studying fictional masters, exchanging roles, watching for breaks in a performance, and revising their assumptions when the evidence contradicts them.

The agency’s theatrical beginnings also establish a durable irony. The Beresfords pretend to be established detectives, while criminals pretend to be inspectors, nurses, clients, or innocent bystanders. In both directions, identity is something presented to an audience and judged from small details—a voice without an accent, a misplaced expression, a conveniently filed letter, a bundle of clothes. Their new enterprise succeeds not because they escape make-believe, but because they learn to notice when make-believe is being used against them.
