Professor Ian Drummond, whose new invention was of interest to the Russians and Americans, is murdered at his Sunshine Menor mansion in full attendance. The writer Joe Alex, who arrived on the eve of the murder together with actress Sarah, and detective Ben Parker, before figuring out the true killer, will suspect in the crime each of those present, because each had a reason for it and there was evidence against each of them.
