Sister Eliza Proudfoot took a job at the special clinic run by Professor Christian van Duyl. She found him a somewhat formidable character, large in build and large in personality! He wasn't precisely overbearing, but Eliza somehow kept getting on the wrong side of him. Which didn't stop her falling in love with him, a mistake when he was engaged to the very suitable Estelle van der Dall. Eliza found Estelle a bit of a bore, but if that was what he wanted, who was Eliza to quibble.
