The Dead Letter Delivery by C.J. Archer

At the end of the last book, Sylvia found a clue to her mother's past. Fairly soon into this book, we have confirmation of her link to Marianne Folgate. Sylvia also gets a link to her grandparents in the form of letters that arrived after they were killed. The first several that she reads are bills but then come several, asking for her mother's hand in marriage. It seems that her mother had magic and word had gotten around. 

There is one man, Reid, who writes first to ask for Marianne to be married to his son, then three years later asking if they know where the is son is. Could it be that Marianne and Robin's disappearances are related?

This line of questioning will take them around London and to an old sanitarium. It's still in use for the soldiers coming back from the war but does it have any connections to the past?
