The Society of Infallible Detectives was a team of the most well known detectives of the late 19th and early 20th century. However, their adventures seemed to have been a parody, in which the detectives proved ineffectual as a team, mainly because each detective insisted on solving the mystery himself. The society was led by Sherlock Holmes and came to order at the society's headquarters on Fakir Street in London. They investigated the robbery of the Mona Lisa painting, as well as other crimes.
