The cable and twist stitch pattern in this classic cardigan pops out of a reverse stocking stitch background. The side panels help to offset the extra visual weight that heavy cabling can add to the figure of the wearer.
I've been asked recently by the folks at Patternfish to explain where my pattern names come from. Most of them are characters in Agatha Christie mysteries. Claire Trent appears in The Red Signal, a short story included in The Hound of Death and Other Stories collection. It was published in 1933.
This collection includes the first appearance of Christie's famous short story The Witness for the Prosecution. The author subsequently wrote a well known play based on this story which has been adapted for both film and television productions.
