Alexandre Dumas 
Derues 

One September afternoon in 1751, towards half-past five, about a score of small boys, chattering, pushing, and tumbling over one another like a covey of partridges, issued from one of the religious schools of Chartres. The joy of the little troop just escaped from a long and wearisome captivity was doubly great: a slight accident to one of the teachers had caused the class to be dismissed half an hour earlier than usual, and in consequence of the extra work thrown on the teaching staff the brother whose duty it was to see all the scholars safe home was compelled to omit that part of his daily task.
