Freak Show Murders

Just as Agent T, I read this when the Crime Club issued it as part of a double novel for Doubleday in 1978.  I read it earlier when it was published by DC Comics as illustrated by M Wm Kaluta in 1974.  Very enjoyable and if you haven't read it then check out this review.  Okay cover, but not a classic.  Digests just didn't have the style of the bigger pulps.
