The Day of Temptation

The Day of Temptation by William Le Queux . He mainly wrote in the genres of mystery, thriller, and espionage, particularly in the years leading up to World War I, when his partnership with British publishing magnate Lord Northcliffe led to the serialised publication and intensive publicising (including actors dressed as German soldiers walking along Regent Street) of pulp-fiction spy stories and invasion literature such as The Invasion of 1910, The Poisoned Bullet, and Spies of the Kaiser. These works were a common phenomenon in pre-WWI Europe, involving fictionalised stories of possible invasion or infiltration by foreign powers; Le Queux's specialty, much appreciated by Northcliffe, was the German invasion of Britain. He was also the original editor of Northcliffe's War of the Nations.
