The curator, a newcomer who specializes in recovering local religious art, enlists Christina's help---but his motives become suspicious when she makes a connection to a string of antiquity thefts from museums along the Santa Fe Trail. Another body surfaces on the banks of the Rio Grande, proving once more that a land steeped in mystery and tradition can be quite deadly as well.
