Sammy Keyes and the Runaway Elf takes place in December, near Christmas. It is the fourth book.


In Sammy Keyes and the Runaway Elf (her fourth adventure, following Sammy Keyes and the Sisters of Mercy ), Sammy gets snookered into dog-sitting Marique, a furry, orange, hoop-jumping Pomeranian, one of the 12 dogs-of-the-month riding atop the Canine Calendar Christmas float. But at the height of the parade, Marique disappears just as three people dressed as the Three Kings throw panicked cats onto the dog-laden float. Chaos ensues, and before the fake snow even settles, Sammy finds herself in the center of a dog-napping scheme, blackmailed by Marique's mean-old-lady owner into tracking the little Pom down before she has to pay $50,000... or else.
