The suspected sabotage investigation moved more slowly than the rumors. Investigators obtained the paint shop's records, spoke with the people who had handled the stripped frame, and examined the recovered insert with an independent specialist. Caleb supplied his original photographs and notes and repeated his observations without trying to make them more dramatic. The specialist confirmed that the alteration was not consistent with ordinary service work and that it had created a serious structural hazard.
The question of responsibility took longer. Skinner denied altering the frame, and Caleb reminded anyone who asked that denial was not proof of innocence or guilt. The records eventually placed Skinner at the shop during a period that had not been included in the original service order, while another witness described a private discussion about making Grip abandon the Nevada run. The evidence pointed toward an intentional attempt to interfere with the motorcycle, but the legal meaning and the full motive required more than gossip in a clubhouse.
Iron Jack called Caleb once to thank him for turning over the evidence in an orderly fashion. The president did not offer details about the club's internal decisions, and Caleb did not ask. He heard later that Skinner had been removed from the chapter while the investigation continued, though he refused to repeat the story as certainty to customers. He had seen how easily a dark shape beside a dumpster became a body in his imagination; he was no longer willing to let stories grow that way in his own shop.
The man who had repaired the red Knucklehead remained important to Grip, but Caleb refused the unspoken role of club confidant. He was a mechanic, not an enforcer, a mediator, or a keeper of secrets. When riders tried to tell him things about rival groups or old grudges, he redirected the conversation toward their bikes. Some took offense at first; the regular customers eventually came to respect the boundary because it made the shop one of the few places where ordinary rules applied.
Two weeks after the Nevada run, Grip returned to Oildale Customs on the red Knucklehead. The specialist had completed the full structural evaluation, corrected the remaining concerns, and supplied documentation that the motorcycle could be returned to service under the agreed conditions. The raw section of frame had been finished professionally, leaving a slightly different shade of red beneath the tank. Grip did not ask for the difference to be hidden.
He parked in the same place where he had first threatened Caleb and switched off the engine. This time he arrived alone. Caleb came out from behind the bench with a clean rag in his hand, and the two men looked at each other across the space where fear had once made every word difficult.
'How's Ruby?' Caleb asked.
'Runs like she remembers being young,' Grip replied.
'And the frame?'
'Checked, documented, and given the old man's blessing.'
