The Dark Angel

Kitty Vane, Alan Trent, and Gerald Shannon have been inseparable since childhood. Both Alan and Gerald are in love with Kitty, who loves Alan in return. The trio's bonds set the stage for the war and romance that follow.

During World War I, Alan and Gerald are drafted and return home for ten days. Alan proposes to Kitty, and she joyfully accepts. Despite his own love for Kitty, Gerald offers his blessing.

With the front line looming, the couple cannot marry officially due to time constraints. They decide to spend one last night together before Alan must return to the war. The plan is heartfelt but tinged with urgency.

Lawrence spots Alan taking champagne and flowers up to a room and assumes he has a woman there, not realizing it is Kitty. The next day, Lawrence teases Alan about the previous night. Gerald, misled, believes Alan has cheated on Kitty and confronts him.

Fueled by anger for Kitty, Gerald refuses to grant Alan leave to marry properly. Instead, he pushes Alan to join him on a dangerous mission. Alan nobly volunteers, choosing duty over his own happiness.

Months pass and Gerald returns home with Kitty, believing Alan was killed in an explosion. The two mourn him together and confront the possibility that they contributed to his fate through misunderstanding and secrecy. Their shared grief brings them closer and awakens complicated feelings between them.

Alan did not die in the explosion; he survived but lost his sight. He is cared for in a German hospital, having adopted the name Roger Crane to keep his family from finding him. A physician, Sir George Barton, begins to suspect the truth behind the alias.

Sir George Barton, an expert in helping blind patients, finds a photograph of Alan with Kitty and Gerald and realizes that Roger Crane is really Alan. He arranges care and begins guiding Roger toward a new life while keeping Alan's past intact.

Alan plans to return to Kitty but chooses to stay hidden, fearing pity. He leaves town and stays at an inn, befriending the innkeeper's children. Inspired by their warmth, he writes a series of successful children's books and eventually moves into his own home with a private secretary.

Sir George visits Alan and sees in the newspaper that Kitty and Gerald are to be married. He realizes that Alan is still in love with Kitty and arranges for a reunion.

Gerald recognizes Roger Crane as Alan, and Kitty and Gerald visit him. Alan initially hides his blindness, leading Kitty to think he has distanced himself. When Alan finally speaks and Kitty realizes he is blind, she still loves him and professes her feelings, while Gerald quietly steps back.
