One idea could be getting her a set of Agatha Christie's books, either in physical form or digital form. Alternatively, you could get her a subscription to a service like Acorn TV, which has a large selection of British mystery dramas, including adaptations of Agatha Christie's novels. Additionally, you could get her a personalised bookmark with her name or initials on it and a quote from her favourite Agatha Christie novel. Lastly, if your mother enjoys puzzle solving, a jigsaw puzzle featuring the cover of one of her favorite Agatha Christie books could be a great idea.
Or you can get her a star map with an important date you share.
