French troops led by one of Napoleon’s best generals are massing on the border. Wellington’s outnumbered force and his unreliable Spanish allies need to pick off the smaller French units if they are to stand their ground.

For that they need information: accurate intelligence on numbers, arms and whereabouts. That’s where Captain Keane and his company of reformed scouting officers are invaluable tools – despite being unpopular with the regular soldiers.

But it soon becomes apparent that someone high up in Wellington’s headquarters is a spy for the French. Only someone able to travel widely outside the camp, someone privy to battle plans, could be the double agent – and Keane’s enemies within the army are quick to point the finger. Keane must defend his crew against their accusers – or root out the traitor himself.

The second book in the Keane series is a fascinating insight into the work of intelligence officers in Wellington’s army. Iain Gale’s matchless military imagination draws a picture of a disparate group of men brought together, in a Peninsular War adventure novel that sees his maverick hero Keane march again.
