Called upon to investigate the brutal murder of a libertine aristocrat, Pepys discovers that the dead man is connected to his mysterious visitor in the most shocking way possible. A trail of secrets leads Pepys from the backstreets of London to the glamorous world of the theatre, where nothing is quite as it seems. But whatever the dangers, he may find that the deadliest threat lies closer to home... Reimagining one of Britain's greatest historical figures through a 21st century lens, Seething Lane is a gripping new mystery from the author of the critically acclaimed thriller The Lost Diary Of Samuel Pepys.
