London, 1922. Theodora Laurent, femme fatale and undercover spy, has spent several months training Lord Rex to be her new partner. It's time for him to undertake his first assignment - finding out who passed along false intelligence to the Cabinet.

Despite Theodora's training, the only thing Lord Rex knows for sure is his spying skills fall far short of hers. However, when London's spymaster himself requests your help, you can't just turn him down.

As a peer of the realm, Lord Rex is the perfect person to take on the search for the loose-lipped politician. Manoeuvring amongst the elite in the halls of Parliament is well within his wheelhouse, promising to be low risk and high reward. Especially, with Theodora at his side.

Or so they think...

But when London's #2 spy ends up dead, their simple assignment turns into a full-fledged murder investigation with England's leading politicians among the suspects.

Just when they think the situation can't get any worse, someone kidnaps the spymaster.

Can Theodora and Rex uncover the treacherous villain behind the murder and kidnapping before they lose their lives?
