On 22 January, 1995, Harry Potter sent Sirius Black a letter by a brown owl informing him about the events that he had seen and overheard regarding Barty Crouch (or so he believed at the time), Severus Snape and Mad-Eye Moody (actually Bartemius Crouch Jr) the night that he visited the Prefects' bathroom to work out his golden egg clue. A brown owl was amongst the owls that delivered hate mail to Hermione Granger in February 1995 following the publication of the article "Harry Potter's Secret Heartache" in Witch Weekly.
