@BelleZora I don't know if you're aware of (or perhaps already have?) Robert Goddard's mystery and suspense series set around the death of an English Diplomat during the early days of the making of the Treaty of Versailles in Paris, 1919.
There is a
free prologue to Book 1 called:
Intersection: Paris, 1919 (An exclusive prologue to The Ways of the World)
This very short introduction also includes chapter1 of Book 1, and is free on
Kobo India (and probably on most country sites)
Neither Book 1 (The Ways of the World) or Book 2 (The Corners of the Globe) are on special, but are both discountable on the India site. (I got book 2 as a pre-order in the heady days of the first India 3 cents sale!!)
