Murder at Breakfast? is the fourth book in author Steve Demaree's Dekker Cozy Mystery Series. In an upscale apartment building for elderly people where residents share their meals in a community dining room a woman has been found poisoned in her apartment. But by the time Lt. Cy Dekker and his partner Sgt. Lou Murdock are called in to solve the murder and an autopsy is done there is not enough evidence to say exactly when or where she was poisoned. It could have been before breakfast, or after she returned to her apartment. Lt. Dekker must question everyone and sift through all the evidence in order to bring the murderer to justice.
