As of my last knowledge update in October 2023, I don't have specific information about an author named Gillian Leggat. It's possible that she is a new or lesser-known author whose works and details have not been widely documented or that she may not be in the mainstream literary spotlight.
To find detailed and accurate information about Gillian Leggat, I suggest checking current literary databases, author websites, or platforms like Goodreads and Amazon, where authors usually have profiles detailing their works and backgrounds. You may also explore social media for authors or writers' groups where she might be discussed.
