According to Manga source: Volume 39: Files 6-8 (398-400)
"Agasa reveals that he knew Haibara's father Professor Miyano through meeting him at conventions. He describes him a friendly man who complimented his inventions. But his wife was the strange one. Her name was Elena and Agasa had heard that she met professor Miyano when she came from England to Japan to study."

Just makes me wonder what is Elena & Mary & Akai family's relationship\connection with England since it was most likely that Mary shrank when she and Sera went to England despite knowing there is nowhere safe to go after Tsutomu went missing? So it's not totally out of the box to assume that RUM may be associated with England and possibly was responsible for Mary's shrinking while she was in England. Given the quick wit and reflexes Mary demonstrated in prior chapters, it seems that it would not be easy to trick or ambush on a woman well-trained in both alertness and combat like her, so... if it was RUM's doing that she shrank... would we be underestimating his\her ability to be able to trick someone like Mary by simply assuming that he\she is a rash and reckless person who screwed up on the mission 17 years ago?
