In this never-before-published mystery, the Hardys swing into action at the summer Olympics when a sinister note arrives declaring I plan to set an Olympic record--fifty-three people will die during these games. Sabotage proves just how serious the threat is, but the Hardys are just as serious about going undercover to protect the athletes.
