Mignon Warner was born in Adelaide, South Australia and in 1982 when Death In Time was published, she was living in London.
Death in Time is set within the confines of a Welsh resort hotel, during a Magician's Conference. Cynthia Playford dies, falling from a cable car travelling up to the local mountain peak early in the morning. It's not so much who would want to kill Cynthia, but who wouldn't as the sister of one of the magicians is not the most popular person.
Nice little book in a cosy / closed hotel style with engaging characters.
