The Falconer and the Partridge
A falconer caught a partridge in his net. The bird cried out sorrowfully, "Let me go, good master falconer, and I promise you I will decoy other partridges into your net."
"No," said the man, "whatever I might have done, I am determined now not to spare you; for there is no death too bad for him who is ready to betray his friends."
