There are serious troubles at Moon Base Alpha. While Dash Gibson and his father are violating safety protocols by throwing a baseball on the lunar surface, to celebrate his 13th birthday, the much hated Lars Sjoburg collapses in the habitat. As it turns out, he has been poisoned with cyanide in his prized Norwegian lutefish and base commander Nina once again forces Dash to help investigate. Meanwhile, the adults are meeting secretly to discuss the declining oxygen supply, which is life threatening so rockets are launched from Earth, but with only enough capacity to rescue half of the moon dwellers. Once again, Dash manages to solve the crime. Finally, the continuing contacts with alien, Zan Perfonic, and her parting was quite endearing. ( )
