Masturbatory Skullduggery 

You enter a room and sniff that familiar smell of ammonia, a copy of Razzle lies open nearby.There are tissues scattered around the bed and underneath the bed is a vacuum-pump penis developer.All the evidence suggests that someone has been wanking them selves off. But who was it?

This case of Masturbatory Skullduggery becomes more incongruous by the minute, some of these used tissues contain wallpaper paste solution!
