The Numbered Account

Julia Probyn, like most people, knew very little about anonymous numbered accounts in Swiss Banks. Until her cousin, Colin Munro, asked her to look into the matter of one containing a fortune for his fiancée Aglaia Armitage, left to her by her Greek grandfather. Julia — journalist, amateur sleuth, occasional spy — must learn fast.
When the account is compromised, and documents of vital interest to the British Secret Service go missing, it is again down to Julia to foil a Communist plot.
In The Numbered Account, book three in The Julia Probyn Mysteries, Ann Bridge brings her characteristic wit, suspense and sense of adventure.
