Dark clouds fill the sky, creating a tense, foreboding mood. Text at the top reads “CAROLYN ARNOLD.” Large white title text in the center reads “DEADLY IMPULSE.” Beneath it: “DETECTIVE MADISON KNIGHT BOOK 6.” At the bottom of the cover, smaller text reads: “A High-Stakes Crime Thriller and Police Procedural.”
