Her Lonely Soldier — Dorothy Black

Young Cicely is married to elderly James. She perches, flutters and strokes his hair while he 'protects' her. She returns a lost diary to a 'lonely soldier', meets him and they fall in love. James dies, leaving his blessing. The soldier is in a fierce battle, feared dead. Cicely meets a kindly Red Cross lady (the Duchess of Rushmere) who persuades her to become a volunteer. She does and, lo and behold, discovers the soldier in the amnesiacs' ward. She decides to cure of him.
