A group of gourmets, who call themselves the Ten for Aristology, invite Wolfe's chef Fritz to cook their annual dinner.
Twelve young women, one per guest, serve the food — they are actresses supplied by a theatrical agency, and are termed "Hebes," after the cupbearer to the gods in the Greek pantheon (later replaced by Ganymede).
For example, the list of possible murderers (here, the Hebes) gaining access to the victim one by one recalls Too Many Cooks, "Fourth of July Picnic" and The Silent Speaker.
Other members of the cast (in credits order) include Colin Fox (Fritz Brenner), Bill Smitrovich (Inspector Cramer), R.D.
