Walking the cat

[Eric Nielsen]

This definition extends the cat metaphor:

"Walk back the cat" is spy slang for retracing the train of evidence and
assumptions until the double agent, the false source or the analytic error
is identified. The cat unraveled the ball of string. Rewind the twisted yarn
to find the flaw."
