HINT 01

    You’ll need another piece of evidence to work out who wrote this letter.

    The letter appears to be written using a typewriter.

    The patient in the psychiatrist reports enjoys tapping away at her typewriter. There appears to be a motive, but is there an alibi?

    Compare both psychiatrist reports.

    The first report states that Nicole is improving in her agoraphobia treatment (a fear of wide open spaces), although it’s very clear that the condition is still rather severe; Nicole is unable to visit the hairdressers without an aide, and even with an aide, she wouldn’t go anywhere near wide open spaces (such as parks) by the time Chloe was killed. The second report states that no improvement had been made since the previous week, and since Chloe was killed in a park, Nicole has a very strong alibi.
