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:
“By metaphor you paint
A thing. Thus, the pineapple was a leather fruit,
A fruit for pewter, thorned and palmed and blue,
To be served by men of ice.”
—Wallace Stevens (1879–1955)
“If we are a metaphor of the universe, the human couple is the metaphor par excellence, the point of intersection of all forces and the seed of all forms. The couple is time recaptured, the return to the time before time.”
—Octavio Paz (b. 1914)
“A theology whose god is a metaphor is wasting its time.”
—Mason Cooley (b. 1927)
