A certain man talks to a certain lady about his sister. He says that she is strange and that she didn't make a cereer as an archeologist. And the woman asks him why is she strange, what happened to her, did she fall ill and that's why she didn't make a career. He replied:
Frankly, no. That came later (her illness).On one of her expeditions something went wrong – I tell you this in confidence; we suspected an unhappy love affair. She returned home completely changed and has lived in virtual retirement
ever since. She reads a great deal and, I think, writes a little: About that she is very secretive. She may very well
“take to” you; she and Mrs Westleton had nothing in common, which was a pity for them both.
Is he trying to say that she writes about her being secretive? No. He is saying that she is very secretive about the fact that she writes.
Does "in common" here mean that they had no common interests? Yes. And because of that they both were sorry about it? No. He is the one who is sorry that they had no common interests and feels that it is unfortunate that neither one benefited from their introduction or meeting.
