Tough cracks and easy cracks, but no impossible cracks

“Tough cracks and easy cracks, but no impossible cracks” is a maxim John Rainbird learns from safecracker G. M. Rammaden and later applies to his pursuit of Charlie McGee. Its decisive significance is the way it turns an art of patient, technical problem-solving into Rainbird’s model for penetrating Charlie’s resistance. The phrase expresses his confidence that persistence and the right approach will eventually work, but its recurrence also exposes the limits and moral cost of treating another person as a lock to be opened.

Origin in Safecracking

During his first year with the Shop, Rainbird takes specialized courses in covert skills, but safecracking is the one that fully engages him. Its instructor, G. M. Rammaden, is an experienced burglar brought from an Atlanta institution specifically to train Shop agents. Rainbird respects his expertise and believes he has nearly matched it. Rammaden’s lessons range from different safe designs and locking mechanisms to practical techniques for working a box open. The maxim condenses that education into a rule of persistence: difficulty varies, but Rainbird takes the possibility of eventual success as fundamental.

Rammaden’s teaching also gives the saying a standard of success more exacting than merely forcing a lock. He recounts two thieves who blow open a supermarket safe but destroy the money inside. As he explains the failure, opening the box is not enough; the contents must remain usable. Rainbird understands the point. In this account, the maxim belongs to a craft governed by attention to both method and outcome. A crude assault may defeat the barrier physically and still fail at the task. That distinction becomes important when Rainbird transfers the metaphor from safes to Charlie: access, not simply force, is what he wants.

Applied to Charlie’s Resistance

Rainbird thinks of Charlie as a difficult safe. The Shop’s attempts to change her behavior involve drugs and extensive psychological attention, but he regards the experts’ efforts as variations on working at the problem from the wrong angle. The safecracker’s vocabulary allows him to interpret a complicated human conflict as a technical challenge: Charlie has a combination, and the task is to discover how to reach it. His confidence in the maxim makes prolonged resistance seem like evidence of difficulty, not proof that his premise is wrong.

The analogy is sharpened by Charlie’s refusal to cooperate. At first, she resists eating, and eventually begins to do so without enthusiasm because continuing to refuse has brought her no advantage. For Rainbird, this change is evidence that pressure can alter her behavior, though it does not mean she has willingly abandoned her opposition. He sees the contest in terms of a crack that has not yet yielded. The maxim thus describes his interpretation of Charlie, not an objective guarantee that she can be made to comply or that such compliance would amount to trust.

Rainbird’s private hopes make the metaphor more disturbing. He feels unusually alive while working on Charlie and is grateful to her for restoring, for a time, his capacity to feel intensely and anticipate something. He expects that he will eventually make her perform for the Shop; after that, he plans to kill her and hopes to find some sign of understanding in her eyes. The maxim’s confidence is therefore bound to a goal that is both instrumental and lethal. He imagines that mastering the difficulty will give him a meaningful encounter, even though the outcome he intends leaves no genuine resolution between them.

The Chisel and the Blackout

The saying returns when a blackout creates an opening Rainbird had not planned. Looking back, he recognizes that the timing could hardly have served him better, but attributes the breakthrough to fortunate circumstance as well as his own intuition. He imagines getting a chisel beneath the psychological steel protecting Charlie. That image turns the maxim into a working strategy: not a direct attack, but an effort to locate a vulnerable edge and gradually create an opening.

During the blackout, Charlie listens to Rainbird describe an ordeal of imprisonment and fear. Her compassion for the wounded man is genuine, and she cries for him as well as for herself and her parents. Rainbird hears the tears and takes them as confirmation that his approach is working. The comparison between a psychological defense and a safe therefore carries an important asymmetry: Charlie experiences an exchange of sympathy, while Rainbird assesses her response as evidence that the chisel has been placed. His confidence rests on interpreting an emotional connection as progress toward access.

Confidence and Its Limits

Rainbird repeats the maxim after he has made Charlie laugh and she again refuses to light fires, holding to her promise not to use her power. At this point he recognizes that continuing to press her may be a mistake that cannot be undone. He is tired, and he compares the effort of working on Charlie with working on one of Rammaden’s safes, but he stops rather than simply assuming that persistence will produce a better result. The moment does not erase his belief in the maxim; it reveals a limit he must acknowledge in practice.

Across these scenes, the expression changes with its application. In Rammaden’s lesson, it is a professional rule about persistence and the usable result of a job. In Rainbird’s thoughts about Charlie, it becomes a rationale for patient manipulation and a measure of his own confidence. The blackout seems to validate his faith in finding an opening, while his decision to stop shows that no method can make every next move safe. The phrase’s grim irony lies in Rainbird’s effort to treat Charlie as a problem that can be solved: even when he believes he has found the combination, his confidence does not make the human consequences of opening the lock controllable.
