Felix Grey and the Seven Assassins

Seven assassins. One election. The fate of the British Empire hangs in the balance. Felix Grey returns in a high-stakes historical mystery of power, politics and murder.

Prime Minister Felix Grey is still reeling from the fallout of his last ordeal, which left his home secretary dead and his own reputation in tatters. With a general election looming, a fragile Labour party emerging, and an odious Tory leader waiting to seize power, he would rather retreat than fight. Duty, however, and the quiet pressure of King Edward VII, leave him with no choice.

As tensions rise at home, danger gathers abroad. In India, demands for independence grow louder, and a shadowy group of seven assassins is dispatched to strike at the heart of the British establishment. Their targets include senior politicians and even the king himself. The message is clear: empire will not be preserved without bloodshed.

Relying on his wits and a loyal circle of allies, Felix must uncover the conspiracy before it tears the country apart. Felix Grey and the Seven Assassins is the second novel in this historical crime series, combining political intrigue, real historical figures, and a high-stakes assassination plot into a fast-paced, witty caper that will delight fans of classic historical mysteries and intelligent, plot-driven fiction.
