David Bond SYNOPSIS A heavy flareup of sunspots interferes with Uncle Martin's control of his levitation and visibility powers. As the sunspots intensify, Uncle Martin becomes invisible and cannot make himself reappear. During Uncle Martin's "absence" an insurance investigator arrives to make a routine checkup on an insurance policy sold by Mrs. Brown (her newest pet project) to Uncle Martin, naming Tim as beneficiary. The investigator grows suspicious when Tim cannot satisfactorily explain Uncle Martin's whereabouts. His suspicions and those of the police are further aroused when circumstantial evidence they discover points to the possibility of foul play upon Uncle Martin by his nephew, Tim. Tim is brought before the District Attorney and questioned on suspicion of having murdered Uncle Martin. The circumstantial evidence against Tim continues to grow and he is about to be arrested for Uncle Martin's murder when the sunspots subside and Uncle Martin is able to make himself reappear at the D.A.'s office door. Martin facetiously explains he has been in a freeway traffic jam all the time -- and Tim is freed.
