A shipping magnate was found dead in his private cabin aboard a luxury yacht anchored in the middle of a calm bay. There were no signs of a struggle. A half-eaten sandwich and a cup of tea rested on his desk. The logbook on the desk was opened to Tuesday. The ship's doctor claimed the man died of natural heart failure on Sunday night. Detective Cole arrested the doctor for murder. Why?
The logbook was updated to Tuesday.
If the magnate died on Sunday night, he could not have written in the logbook on Tuesday. Someone else updated the logbook after his death.
