Mr Mystery #19: The Mystery Of The Museum Murder

Who murdered Dr Lai in the museum? Why did his killer use a poison dart? What caused all the security systems to fail at the time of the murder? A poison dart, shot from a blowpipe, kills Dr Augustus Lai at midnight in a museum. When Alvin Soh and his investigators start tracking down a dangerous killer, a second murder makes the mystery even more baffling. Who wanted Dr Lai dead? Was it one of his colleagues or an intruder? Why had he wanted to call Alvin before his death?
