The Dead Ringer

Three murders were too many for Ed Hunter. Not even a dazzling redhead from the carnival's girl show could keep Ed altogether happy--not with a murderer running loose. Then Ed found it was up to him and his Uncle Am to find the killer among the freaks and strippers of the carnival--a killer who chose his victims according to size!
Ed and his Uncle Am are back, working in a travelling carnival through the Midwest. Bodies, though smallish in stature, keep piling up, and Ed finds himself head over heels in love. Fascinating for the insights into carnival life that this book provides.
