Murder Weekend
During a recent murder mystery weekend, four games were played.
In one game Mrs Scarlett used the spanner, but not in the library.
In another game the rope was used in the study, but not by Col. Mustard.
During one game the gun was used in the conservatory, whilst in another game Prof. Plum was not to be found in the library.
Col. Mustard was never in the conservatory and Miss Peacock never used the rope.
The lead piping may or may not have been used in the kitchen.
Who used what and where?
