Detective Sarah Mercer returns for five more gripping cases, each pulling her deeper into a pattern of secrets stretching across London.

From a stack of unopened letters to a dinner party where everyone is hiding something, from a courtroom verdict that doesn't add up to a reckoning that has been years in the making, Sarah's instincts are tested like never before.

As the cases pile up, the threads connecting them grow harder to ignore — and Sarah begins to realise the truth she's chasing may lead somewhere she never expected: back to herself.

Perfect for fans of atmospheric British crime fiction and detectives who refuse to let a case go cold.
