Stark terror and mysterious death follow in the wake of an
unseen demon, which lurks in the city streets and houses,
whispering in the ears of its victims before killing them.
Medical examination shows that they were, apparently, strangled
to death. One of the victims, before dying, declares the breath
of the Whispering Thing is icy cold. Nobody has seen it. Nobody
can imagine what it is. Then Jules Peret, French detective who
is in America, undertakes to fathom the terrible mystery. After
his preliminary investigation, he goes home, and when he enters
his darkened rooms he feels an ice-cold breath on his cheek,
and he knows he is in the presence of the Whispering Thing.
