Bestseller Mysteries are one of those semi-collectible things that show up in groups now and then. Not super valuable, but cool. They always have a little snippet of a blurb from some review on the cover and going through a stack of them earlier I was amused by the shared tone of moderation.
"The mixture is admirably blended." - NYT
"Extremely readable." NY Herald-Tribune
"...seethes all the time." NY Herald-Tribune
"Luscious lasses add spice to cunningly compounded plot." - Saturday Review
Hardly the level of nearly depraved enthusiasm one expects from the artform!
