This novel had me in stitches. Helen's lover of four years decides to leave his wife. Great most mistress's would think, but Helen was beginning to wonder if the relationship had run it's course. What she doesn't know is that Matthew is a serial monogamist, who likes to have his next "relationship" lined up, before leaping out of the previous one. The novel tells of Helen's attempts to untangle herself from Matthew, and she just ends up digging herself into more of a tangle. A good light read, with enough to keep your attention.
