A tripwire is a passive triggering mechanism. Typically, a wire or cord is attached to some device for detecting or reacting to physical movement.
A tripwire may be a wire attached to one or more mines — normally bounding mines and the fragmentation type — in order to increase their activation area.. Alternatively, tripwires are frequently used in boobytraps, whereby a tug on the wire (or release of tension on it) will detonate the explosives.
Soldiers sometimes detect the presence of tripwires by spraying the area with Silly String. It will settle to the ground in areas where there are no wires; if there are any, the string will be suspended in the air but not set them off due to its light weight. It was used by U.S. troops in Iraq for this purpose.
A newer method is the use of green line lasers to illuminate and detect trip and command wires. The bright laser line creates a fluorescence that can be seen by the bomb tech.
Tripwire is the third book in the Jack Reacher series written by Lee Child. It was published in 1999 by Putnam in America and Bantam in the United Kingdom. It is written in the third person.
The prologue describes Victor Truman "Hook" Hobie's carefully planned escape route in the event of somebody discovering his really big, well-guarded secret. His "early-warning system" consists of geographically-located "tripwires". The first tripwire is eleven thousand miles from home and the second tripwire is six thousand miles out. His response to their activation would be to tie up loose ends, cash in, transfer assets and flee the country. Over 30 years of quiet success have made him feel somewhat secure. But then the two tripwire alerts arrive on the same day.
The main story begins with Jack Reacher working two jobs in Key West and bumping into a private detective who happens to be searching for Jack. Costello is working for a client named Mrs. Jacob, a name Reacher does not recognise. Later on, whilst Reacher is working his night job as a bouncer in a strip club, two very suspicious-looking men also make inquiries about his location. Reacher attempts to follow them but instead finds Costello murdered on the sidewalk. Jack then flies to New York to find out why Costello was looking for Reacher and why he was killed for it.

Good old General Hand Grenade
Ridin' in a motorcade
Sippin' on a lemonade
And waving at his fans
Isabella Band Aid
Wavin' at the Shrine parade
Eatin' toast and marmalade
And getting sticky hands
Good old General Hand Grenade
Ridin' in a motorcade
Lookin' for the cavalcade
To take him off to war
Isabella Band Aid
Suckin' on a Gatorade
Lookin' at the mess he made
And wonderin' what it's for
People gettin' high
People gettin' low
People gettin' nowhere
'Cause they don't know where to go
Good old General Hand Grenade
Ridin' in a motorcade
Lookin' for the cavalcade
To take him off to war
Isabella Band Aid
Suckin' on a Gatorade
Lookin' at the mess they made
And wonderin' what it's for
