A murdered clerk. A body at Waterloo. A letter with a deadly secret.

London, 1889. In the gloomy Dead Letter Office at St Martin’s Le Grand, young clerk Andrew Peverell spends his days sorting through letters that never found their intended reader. When three anonymous notes cross his desk – each inviting a stranger to a public house near Buckingham Palace – Andrew makes a decision that will cost him his life.

Four days later, a foul smell leads to a black leather trunk in Waterloo Station’s left-luggage office. Inside is Andrew’s body.

When the story reaches the morning papers, Emma Langley recognises the victim’s name – a man her late brother once knew as a boy. Together with her friend Penny Green, she sets out to find the truth. Their investigation takes them from the hushed rooms of the Dead Letter Office to the grand halls of Marlborough House, where a footman has vanished and a menacing lawyer is hunting him down.

But the truth about Andrew’s death lies somewhere no one has thought to look. And by the time Emma understands what she is really searching for, the killer is closer than she has ever imagined…
