Virginia Woolf's Door

Origin
Virginia Woolf was a significant figure in London literary society and one of the most famed in 20th century literature. Her most famous novels include Mrs Dalloway, To the Lighthouse and Orlando. Another piece is the book-length essay A Room of One's Own with its famous quote, "A woman must have money and a room of her own if she is to write fiction." She suffered from depression and possibly bipolar disorder and committed suicide by drowning at the age of 59.

Effects
A door that opens up into a personal room for anyone that opens it. Nobody can enter another's room unless the person who the room belongs to holds the door open. It may cause the user to hear voices after prolonged usage, but the agent who prompted that theory had also accidently brought in J. Edgar Hoover's Telephone into the room, so it is unknown which of the two artifacts caused it.
