This is the last book in the Duncan Sister Trilogy. The first two books are The Bachelor List & The Bride Hunt which tell the stories of Constance and Prudence Duncan. This trio of sisters has had to find ways to supplement their income after their father loses a large portion of his wealth on a bad investment. The stories take place in the early 1900 which was quite different for me. There really aren't that many books that take place during this time, when the women's suffragist movement was taking root and women were testing the limits society had imposed on them for so long. The sisters decide to continue the suffragist work their deceased mother had started by printing a broadsheet called The Mayfair Lady where not only do they talk about the movement but also run advertisements, an advice column and a matchmaking service. The Go-Between is the matchmaking service which we have seen has had some success in the previous books.
The book covers Chastity and Douglas romance, but also Lord Duncan's (the sister's widowed father) romance to an Italian Countess, whose daughter, Laura, is the candidate the Go-Between have chosen for
