Talents, Incorporated is a science fiction novel by Murray Leinster first published in 1962.

Bors felt as if he'd been hit over the head. This was ridiculous! He'd planned and carried out the destruction of that warship because the information of its existence and location was verified by a magnetometer.

He'd have dismissed it flatly!
