As Queen Victoria lies dying, Montmorency and his friends are already in mourning, and determined to track down the killers who have wrecked their lives. It's personal obsession, but Montmorency has public duties too, and when the two collide, he must decide which comes first.

Can he stop Doctor Farcett's slide into insanity? And how can he teach a new generation to forgive when the lust for revenge is eating away at his own soul?

The fourth Montmorency adventure takes him on a race across the globe with a mission of revenge for the death of his dearest friend Lord George Fox-Selwyn.
