The Gripping Hand
Jerry Pournelle
 At the end of The Mote in God's Eye, Renner and Bury are secretly enlisted into Imperial Naval Intelligence. They spend the next twenty-five years investigating revolutions against the Empire so that the Imperial Navy can concentrate on blockading the Moties from entering into human space. While investigating economic abnormalities on the Mormon planet Maxroy's Purchase, Renner and Bury encounter widespread use of the phrase "on the gripping hand". While the source of the phrase turns out to be innocuous enough &mdash; the Governor picked up the expression as an Able Spacer on INSS MacArthur on the expedition to Mote Prime &mdash; the memories dredged up by the incident are too much for Bury. Driven by nightmares and a deep-seated fear for humanity's safety, Bury must confirm that the Empire is safe from the Moties. Renner and Bury travel first to Sparta, the Imperial capital planet, to obtain permission to inspect the blockade. Along the way, they discover widespread interest in a second expedition to the Mote, as well as disturbing evidence that the blockade may soon fail. In Mote, it is mentioned that a protostar is forming in the Coalsack Nebula. The Moties had studied it extensively and told the MacArthur expedition of their estimate that it would ignite in about 1,000 years. That estimate was deliberately falsified - the object was about to collapse and ignite at any moment. The newborn star would mean that a new Alderson Point would be created for interstellar travel, allowing the Moties a second exit from their system. Previously, the only Alderson Point accessible to them was positioned in the photosphere of the supergiant red star, "Murcheson's Eye", making a human blockade practical since the Moties had not stumbled onto the secret of the Langston Field. Armed with the alarming new knowledge and carrying influential passengers, Renner, Bury, and their ship Sinbad depart for New Caledonia, the closest human system to the Mote. There the Imperial Commission decides that ships must be sent to the hitherto ignored star system where the new Alderson point is predicted to appear. Sinbad is among the ships dispatched. The point appears soon after the small, hastily assembled Imperial fleet's arrival—and so do the Moties. The second half of The Gripping Hand is a convoluted tale of alliances, diplomacy, trade, and space combat between the Empire, led by Bury and Renner, and the many, many factions of Motie civilization. With the aid of the children of Lord and Lady Blaine, and an impressive piece of genetic engineering, Bury and Renner fight to stabilize the Mote civilization and save the Empire. At the end of the story, the Moties insist that they have to choose between the two equal but unpleasant options of staying bottled in their home system, or expanding and spreading their eternal war through the galaxy. The humans exploit the Moties' idiom of "on the gripping hand" to present a third, stronger option: a genetic modification that would slow down the excessive reproduction rate of the Moties so that they can expand peacefully.
