Heart of Brass

Arden Grey, Lady Huntley, has the status, wealth and independence of a countess — and a secret gift: she can see the final moments of a murder victim's life. She uses it undercover for the Wardens of the Realm, who protect a steam-powered England in 1898, while her husband Lucas remains missing.

Then Arden spots Lucas one night on the streets of London. The Company, the Wardens' enemy, has wiped his memory and sent him to kill her. He finds he cannot do it — but if he does not, someone else will kill her, and him.

Heart of Brass is the first of Kate Cross's Clockwork Agents novels, followed by Touch of Steel and Breath of Iron.
