Enact a new subrule to Rule 2.11 (The Reading of the Will), titled “Calling the Police”:-

There are suspicions that the Executor orchestrated Lord Cartlesham’s murder with the help of several accomplices, and this revelation would render the will void if proven.

As a weekly action, and if the Lights are On, a Guest who is in the Parlor and who has never been a Murderer may telephone Scotland Yard with his or her suspicions regarding Lord Cartlesham’s death. To do this, they must make a GNDT comment of “Using the telephone” and send a telegram to the Executor with a list of Guests - this is known as a Suspect List.

Upon receiving a Suspect List, if the list includes the name of every Guest who has been a Murderer this Dynasty (including idle Guests), and does not include the name of any Guests (including idle Guests) who have never been a Murderer this Dynasty, then the Executor shall announce this correct identification to the weblog, naming the Guest who made the phonecall. The Executor shall change the state of any Murderers currently in the Manor to “Arrested”, and the Guest who made the phonecall achieves victory.

In Rule 2.2, add “Arrested” to “Healthy, Poisoned or Dead” and “Healthy, Restrained or Dead” (so that Poisoned and Restrained Guests can still be Arrested).
