The main character was a woman with red hair, who thought she was a twin, but by the end of the book she finds out that she's actually a triplet. I THINK her siblings were a sister and a brother. I THINK she knew about the sister and it was the brother who was the surprise triplet at the end.-- The theme of the book is "acting as if" -- If you "act as if" something is so, it can be so.
-- I THINK she was taught this lesson by her boss, and I THINK she dated this boss, or maybe just wanted to.
Even these scant details are fuzzy to me and I'm not sure of anything except the phrase "acting as if." I can guarantee that this was not any kind of real literature that would have any reason to still be in print anywhere. I read it as a teenager in the early 70's, and it was one of those cheap paperbacks that don't hang around. Thanks for your help!!!
