Maurice Leblanc was a French author who lived from 1864 to 1941 and was one of the first people to write mystery stories. He is best known for creating the famous character Ars ne Lupin, a smart and stylish gentleman thief who is often compared to Sherlock Holmes in France. The first Ars ne Lupin stories by Leblanc came out in the early 1900s and quickly became very popular thanks to their smart plots, wit, and likeable main character. In Leblanc's body of work, "The Teeth of the Tiger" stands out. This book is different from the Ars ne Lupin series. It's an exciting and suspenseful story set in the early days of World War I, when there is espionage and political intrigue going on. A story called "The Teeth of the Tiger" is about three friends who get caught up in a web of political plots, foreign espionage, and secret codes. Leblanc cleverly mixes mystery, adventure, and espionage to make a gripping story that shows how worried and uncertain people were during the war.
