The Bromius Phenomenon

Senior Controller Dag Fletcher was involved as soon as Interstellar Two Nine disappeared in the gravisphere of Bromius. There must have been more to the loss of the starship than navigational error or mechanical failure. An ethnological mission couldn't have got into that much trouble. This was an ideal opportunity to get back in the thick of the action, and put Hulda out of his mind once and for all. He knew the Bromusians as a cheerful and sociable race and it seemed unlikely and quite incredible they might be involved in interplanetary intrigue. But then again, Hulda was part Bromusian. This is the fourth book in the Dag Fletcher Galactic series.
