High Wall

The strangulation death of Helen Kenet, outwardly looks to be a simple case to prosecute her husband Steve Kenet, whom she married following a whirlwind wartime romance, for her murder. Steve, a fighter pilot during the war, had just returned after being away for two years on a flying job overseas in Burma. Following the war, he took that job rather than the alternative of a local underpaid academic job. While Steve was away, Helen, bored at home while Steve's mother looked after their now-six-year-old son Richard Kenet, got a job as secretary to Willard Whitcombe at Brattle Press, which publishes religious educational textbooks. Against the wishes of District Attorney David Wallace, Steve is sent to a psychiatric hospital for evaluation as he is seen to have previously had a head operation, it done during the war to deal with an injury. There, he is placed under the general psychiatric care of Dr. Ann Lorrison. Dr. Lorrison and her team discover that there are medical issues which have caused among other symptoms lapses in Steve's memory; he doesn't remember the events surrounding his encounter with Helen upon his return. These medical issues can be treated through further operations which Steve could have done long ago but refused, leading to Wallace believing that Steve had all along wanted to use these as excuses in truly wanting to murder Helen and being able to claim temporary insanity in a court to get off scot-free. As Steve's treatment progresses, both he and Dr. Lorrison, without either stating it, believe he did kill Helen. Something twigs in his brain that perhaps he didn't, so he tries everything to discover the complete truth, mainly for Richard's sake, but it will not be easy, with his incarceration and someone else not wanting him to discover the truth. As Ann starts to believe that Steve is innocent, she and he have the competing priorities of his overall mental and physical welfare versus justice in putting the right person behind bars.
