The crime scene was set,
the usual suspects had all RSVPd,
upon the dining table the petit fours were gathered in pairs,
at a side table the pears were floating in a strangely
poisonous concoction that defies description,
all else was as normal as a white elephant
stalling the Black London Cab that they had recently stolen.
Add in some detail.
Give everyone a motive – and an alibi.
Draw the chalk outline in expectation of the victim’s fall – similar to ‘pin-the-tail-upon-the-donkey’ and cut the telephone wires.
Sack the butler – it gives him more of a possibility of having done ‘it’.
Cable distant relatives, mentioning the huge inheritance, and the missing will.
Provide Cluedo ‘Detective Sheets’ for the guests, making sure that there is already a body in the library and sparkling cyanide on tap.
