Pat Riordan has been named a person of interest in a missing woman case. Detective Sergeant Donald Cromwell says Riordan is also likely guilty in the disappearance of two other women. Fired from his teaching position, Riordan sets out to exonerate himself as Cromwell builds a case against him. Accompanied by a stray dog, Riordan prods onward through unexplained encounters. Pieces start to fall into place, but answers lead to more questions. This is the second book in the series of The Pat Riordan Stories, but the first in which the teacher turns sleuth.
