That's a very good point about Carruthers not having much money - very carelessly I overlooked he was probably not living within his means. There might be enough to send his daughter to boarding school for a few years - and I rather think Violet would pay any shortcoming. The daughter could holiday with Violet and Cyril.

(I call Carruther's feelings a crush, rather than love, not only for his selfishness but because he was thinking only for the short term. Suppose he had married Violet? Another case for Sherlock Holmes. If she didn't find out about Carruther's lies, Woodleigh would have blackmailed some or all of her inheritance out of him; and sooner or later Holmes would have been called in about this mysterious red headed corpse...)
