In 1989 in Chicago, nine scouts vanished at camp. 22 years later, Park Ranger finds this park ranger. William Hayes pulled his truck to a stop beside the overgrown trail marker. 22 years of service at Forest Glenn Preserve had taught him to notice things others missed. Today, the autumn cleanup had revealed something that shouldn't be there. “Bass, this is Hayes on Trail 7,” he spoke into his radio. “I need Detective Chen down here. Found something she needs to see.” The response crackled back.
