Cormoran Strike’s leg injury, sustained while serving in Afghanistan, results in the loss of his calf and foot and the use of a prosthesis. It is not only a past military wound: it continues to govern how he walks, dresses, manages pain, and moves through civilian life, while marking the difficult transition from the army that formed him to a precarious existence in London.

Injury and Departure from the Army

When asked why he left the army, Strike gives the simplest account: his leg was blown off. He recognizes that this is only part of the truth. The injury precipitated a decision already approaching: he had begun to feel that if he stayed much longer, civilian readjustment would become too onerous. Years of military life had shaped him almost imperceptibly, making it easier to be carried along by its force, but he had never been entirely absorbed by it and chose to leave before that happened.

The loss of his lower leg therefore marks both a physical rupture and a turning point in his service. Strike retains an unaffected fondness for the Special Investigation Branch despite the injury and his departure. The wound does not erase his attachment to the institution; instead, it stands alongside a choice to leave that had been forming before the amputation made the change immediate.

The Prosthesis in Daily Life

The prosthesis is a practical necessity whose fit and use have consequences throughout Strike’s routine. After a long, inexpensive walk across London carrying his kitbag, he develops chafing at the end of his stump. He later searches through boxes outside his office for dermatological products to soothe its burning and prickling. When he reattaches the prosthesis, it is extremely painful, and walking down Charing Cross Road becomes harder still. Although he finds the grey metal sticks issued when he left Selly Oak Hospital, he disdains using them.

His body also affects how he chooses to occupy public space. At a university swimming-pool changing room, he waits for a quiet moment rather than showering in full view of students, because he does not want his false leg to become a distinguishing feature in anyone’s memory. He deliberately makes himself look intimidating as he passes the desk. His concealment is not simply a matter of movement: it is an effort to control how others see the injury and what they remember about him.

Strain, Money, and Isolation

The injury is affected by changes in Strike’s body and circumstances. He has gained a stone and a half, feels unfit, and knows that the extra weight places unnecessary strain on the prosthesis. It causes chafing and leaves him developing the shadow of a limp. The long walk with his kitbag aggravates the damage, while his need to travel as cheaply as possible reflects the financial insecurity that accompanies his life after leaving the army.

Strike describes himself as having lost the army, Charlotte, and half a leg. In the aftermath, he feels that he must become accustomed to the man he has become before exposing himself to other people’s surprise and pity. His social world contracts; Robin is his only real human contact, and he is not ready to resume a proper social life. The injury is thus one part of a wider upheaval, but its visibility makes it a recurring point of tension between his private adjustment and other people’s gaze.

Recognition and Military Kinship

The injury also gives Strike a basis for recognition with Lieutenant Jonah Agyeman, a soldier whose sister’s death has brought him back to Britain. When the two meet in a pub after the arrest of his sister’s murderer, both have lived military lives and risked the same death. Their conversation turns for half an hour to the army, a subject that establishes a bond unavailable to civilians.

The scene places Strike’s injury within a continuing military identity rather than treating it as a condition that wholly defines him. His prosthesis, pain, and altered mobility remain concrete features of his life; at the same time, his experience of service allows him to meet Agyeman through shared understanding. The injury is both a lasting physical consequence and one strand in the ties Strike carries from the army into civilian life.
