There’s a book called “the go between” by LP Hartley, about a 60-year-old man remembering a summer he spent in 1900 at a manor estate as a lower-class 12 year old boy. People staying at the estate (upper class) used the main character to carry messages between them to arrange meeting for sexual encounters and stuff. It’s a good book (often taught in high schools, where I was exposed to it first).
There’s a concept in the book, where the character is related (I think) to a greek or roman god, but I cannot recall which one it is. Basically, he acted as a go-between for the big gods, hence it’s relation to this book.
So the question is, what’s this go-between god’s name?
