Read the excerpt from The Dark Game.
On several occasions Room 40 received an
unexpected but welcome gift when a German
codebook was recovered after a sea battle and
presented to the British code breakers. One such gift was a codebook from the German ship Magdeburg, a light cruiser that ran aground on an island off of Finland. When Russian ships quickly bore down on the cruiser, the captain of the stranded ship immediately
did what all naval officers were taught to do: he ordered his signalman to bring him the ship's codebook so he could throw the book, wrapped in lead covers, into the
sea. But before the signalman could deliver the book to his captain, he was killed by Russian guns. When the Russians recovered his body, the sailor was still
clutching the codebook in his arms.

What is the Dark Game?

This book provides a factual chronicle of espionage in the US throughout the Revolutionary War until the twenty-first century's close. It impresses with its intriguing tales and is richly photo-illustrated. Accounts about women's espionage and their lifestyles are particularly fascinating.

Whenever a German codebook was found after a naval battle, Room 40 was given an unexpected but pleasant surprise. The German warship Magdeburg, which is grounded on a tiny island in Finland, left behind this codebook.

The captain asked his signalman to bring him the manuscript, but the Russians shot him dead so he could do so. The sailor had the codebook concealed in his hand before the Russians discovered his body. Therefore, option C is correct.
