title has an exclamation mark, or "shriek" - which was perhaps peculiarly apropos to the horror boom of the late seventies through the mid-eighties. . .
this st. martins press mmpb edition was prob'ly published in 1989, not 1985;
might a bookcatter with, or with access to a copy kindly look at its indica, and report?
n.b. in travelling across the pond, the book lost its shriek!
