Remus Carey never learns the name of the nurse who looks after him on the boat to which he is transferred after being removed from The Dalliance. However, he suspects from the way that she acts (discreetly) that she may be a useful ally in the long run.
Although she is sturdy and carries a little more weight than her height would suggest was appropriate, she is very light on her feet. As described in book 2, Blowfish,
She pressed the handle and there she stood: big and strong, built for hauling bariatrics out of their sagging bunks. She carried herself in almost impossible silence, padding about on trunk-like legs without ever scuffing the floor… I looked down, expecting to see tights and toes, but her feet were tied up in neat white plimsols that matched her apron and smock.
Her mother tongue is assumed to be German, although she manages to converse with Remus in English, as she doesn’t understand his mother tongue, Guernesiais.
She appears to work with a male orderly, although Remus never learns his name, either, or gets a particularly clear look at his face the one time he encounters him.
