Enact a new rule, “The Murder”:-

The Murder of Morgan Chamberlain has four Qualities: a Location, a Method, a Murderer and a Motive. These values of these Qualities are tracked privately by the Chief. Each valid value of a Quality is known as a Possibility.

The Murder’s Location may be either the Dining Room, the Lounge, the Kitchen, the Study, the Hall, the Billiard Room, the Conservatory, the Ballroom, the Library or the Cellar.

Its Method may be either Firearm, Knife, Beating, Blunt Object, Strangulation, Fire, Poison, Drowning or Explosives.

Its Murderer may be Casey, Morgan Junior, Benjamin, Elizabeth, Isabel, James, Joshua, Anne or Robert.

Its Motive may be Hatred, Jealousy, Wealth, Self-Defence, Politics, Revenge, Accident or Sociopathy.

If he has not already done so, the Chief may set all Qualities of the Murder to secretly random values, and then delete this sentence from the ruleset.

Enact a new rule, “Clues”:-

When a Detective finds a Clue, the Chief selects a Possibility at random and privately informs that Detective of that Possibility: if the Possibility is a Quality of the Murder it is described to the Detective as “Proof”, otherwise it is described as “Disproof”.

If the Chief has not done so in the past 72 hours, he should perform the following atomic action, known as a Search:-

* For each Detective, roll a ten-sided die: on a result of 6 or higher, that Detective finds a Clue. (This is known as the Search Roll.)
* Post a blog entry announcing that a Search has occurred, and how many Clues were found during it.

(Whenever the Chief resolves something at random, that decision is secretly random.)
