« I was never happier than when I fell asleep, after a good meal, in my mother's big bed at Blenheim. »— Winston Churchill, My Early Life, 1930
Your investigation begins in Woodstock, at the foot of the Triumphal Column, near Blenheim Palace. This 41-meter-high column, erected between 1727 and 1730 by the Duke of Marlborough and Sir John Vanbrugh, is dedicated to John Churchill, 1st Duke of Marlborough's victory at the Battle of Blenheim in 1704. It is here, in the heart of the Oxfordshire estate, that the initial information about the plot is transmitted to you. The Blenheim Palace archives mention suspicious movements and encrypted correspondences that put you on the trail of a spy cell.
Blenheim Palace's Great Court, with its early 18th-century Baroque facade, becomes the scene of your next investigation. Winston Churchill was born in this palace in 1874, and spent part of his childhood there. The gardens and courtyards of Blenheim Palace have been silent witnesses to his thoughts and strategies. You will need to find clues hidden in the architecture, as if the stones themselves whispered the secrets of the Churchill family. Your route will lead you through this historic site to unearth concealed evidence.
The interior of Blenheim Palace, residence of the Dukes of Marlborough, is your next stop. This UNESCO World Heritage site is a monument of British history and a central place for understanding Churchill's ties to aristocracy and power. In 1940, the palace was briefly proposed as a refuge for the royal family, attesting to its strategic importance. You will look for symbols and codes that might be related to the plot, exploring the rooms where Churchill himself walked, from the Great Hall to the Long Library.
Your path then leads you to St Martin's Church in Bladon, the burial place of Sir Winston Churchill and his wife Clementine. This location, a few kilometers from Woodstock, is an essential stop to understand the Prime Minister's legacy. Although modest, this 12th-century parish church, largely rebuilt in the 19th century, symbolizes Churchill's attachment to his native Oxfordshire. You will find a personal message, hidden near his tomb, which could unlock the rest of the investigation and reveal the conspirators' identity.
Back in Woodstock, The Bear Hotel, a former 13th-century coaching inn, awaits you. This establishment has hosted many influential figures throughout the centuries, and its walls have witnessed discreet conversations. In 1940, it could have served as a secret meeting point. You will uncover clues left by the conspirators, perhaps in the form of a forgotten object or a coded note. Your circuit will then take you to the ruins of Woodstock Palace, a former royal palace that hosted Henry II and Edward III, where medieval remains hold the final pieces of the puzzle, allowing you to thwart "Churchill's Secret Plot" and protect the Prime Minister from this insidious threat.
