A group of people are murdered during an apparent holdup. Upon further investigation there emerges a set of coincidences linking several of the victims. One of the victims is a woman who was engaged to be married to the nephew of a textile magnate. The woman was also an old flame of the investigating detective. A marvelously coloured sweater appears to tie everything together, but what is the nature of the tie. This episode had a lot of potential, but seemed to fall short in execution.
