A quick look at the composition. Note how there is no detail in the background. The artist is creating space by adding more detail as the visual space gets closer to the viewer. The artist had fun here with the flash of the bulb. It allowed him to place some visual distance between the foreground object of the camera and the background object of the couple on the bed.
Nothing pops an item forward like black on white.
Then that nice distancing blend of blue to the bed. The artist connects the light by making sure that white is used in short splashes on the shirt and nightgown, and even into the plain yellow background. You have to wonder who is being set up here, the man or the woman. Perhaps that little question was one of the marketing honcho's idea of luring you into reading the book. When Kent Murdock, news cameraman who doubles as a dick, steps into a case, there's always plenty of fast talk and fast action.
