WHO: Dumbledore and Order Members
WHAT: A Patronus Message
WHEN: Sunday Afternoon
WHERE: Their respective homes
The Phoenix Patronus swooped into the room and stopped. For each member in the privacy of his own home, the message began immediately. For those who were not, the Phoenix shrank into a glowing ball of light and guided them to a private place where charms would be needed to ensure secrecy.
When each recipient was ready, Dumbledore's voice spoke calmly. "The next meeting of the Order of the Phoenix will be held in the basement of the Three Broomsticks on Tuesday at seven."
