The church lay in the heart of the city.-- The Hidden Target by Helen MacInnes.
I always love her books. Everyone is dashing and debonair, the women wear dresses and high-heeled pumps but can still can outrun bad guys, and the stories are a little racy with some European flair.
This one involves "a new undercover counter-terrorist network" and "a deadly game playing across thee continents." It was published in 1980, so won't have the kitschy, Mid-Century charm of her earlier books.But I'm sure I will still love it.
