Blurb from the book jacket; "After a misunderstanding terminated her engagement to an austere clergyman in Cornwall, schoolmistress Clarissa Herbert fled across the Channel to tutor the daughter of an English Lord in the diplomatic corp, but the position she won as his interpreter seemed a blessing until espionage and murder stalked the railroad journey to St. Petersburg. Richly atmospheric and suspenseful." A really good mystery and some romance with a couple of surprises at the end.
