Mason gives Della Street two weeks vacation! That is, it was supposed to be a vacation, but Della turned it into a busmans holiday.Target of interest was a well-stacked blondeone who incredibly stashed away five enormous meals a day. Her name was Dianne, and when Mason unexpectedly appeared, he and Della discovered she had signed a contract to gain weight quickly in order to model clothes for stylish stouts. Perry smelled a rat, and when he read the contract he found a nest of them. One led straight to murder.
