Trouble

Tom Lionel is a consulting engineer who wakes up one day to find his life has become considerably more complicated: there's another man living in his head. His name is also Tom Lionel, but this one is a physicist, obsessed with impractical theories and expensive equipment that threaten to bankrupt them both. While the engineer tries to actually build things and meet payroll, his alter ego hijacks the laboratory to chase poltergeists and experiment with antigravity. The two personalities warily coexist, each convinced the other is completely mad. But when genuine scientific disaster strikes and neither the practical man nor the theorist can solve it alone, they're forced to admit that maybe the enemy in their own skull is also their best hope. George O. Smith writes with sharp wit and genuine affection for the absurdity of brilliant men destroying themselves over ideas.
