Metaphor
Figuratively, a cloak may be anything that disguises or conceals something. In many science fiction worlds such as Star Trek and Stargate, there are cloaking devices, which provide a way to avoid detection or to make an object appear invisible.
Because they keep a person hidden and conceal a weapon, the phrase cloak and dagger has come to refer to espionage and secretive crimes: it suggests murder from hidden sources. "Cloak and dagger" stories are thus mystery, detective, and crime stories of this. The vigilante duo of Marvel comics Cloak and Dagger is a reference to this.

Famous quotes containing the word metaphor:
“Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.”
—Johan Huizinga (1872–1945)
“—fur-petalled chrysanthemum,
squirrel-killer—
is a metaphor only if I
force him to be one....”
—Denise Levertov (b. 1923)
“A theology whose god is a metaphor is wasting its time.”
—Mason Cooley (b. 1927)
