It's the week of Fiesta in Santa Fe and Maddie is looking forward to enjoying the celebrations. But as 'Old Man Gloom' Zozobra goes up in flames, so too do Maddie's hopes for a carefree life . . . Human remains are found in the dying embers of Zozobra, and then Maddie and her dashing beau Dr David Cole find a body washed up in the arroyo at the edge of town.

Soon identified as Ricardo Montoya, a wealthy businessman and head of one of the most affluent families in Santa Fe . . . the plot starts to thicken. While his beautiful wife Catalina and her complicated children seem less than heartbroken at his untimely demise, and with many disgruntled locals crawling out of the woodwork, Maddie is surrounded by suspects.

With the celebrations of Fiesta continuing around them, Maddie and her 'Detection Posse' get busy infiltrating the best parties and hobnobbing with old and new faces - but can they bring the murderer to justice before they strike again?
