146 W H A T EVERY BODY IS SAYING
BOX 39: WHERE THERE’S (JITTERY) SMOKE, THERE’S FIRE
During my work on a major espionage investigation, I was interviewing a
man of interest in the case. As I watched him, he lit a cigarette and began
smoking. I had no real clues with regard to his possible connection to the
case; there were no witnesses to the crime, no significant leads, and only
vague ideas of who might be involved. During the interview I brought up
many names of people who were of interest to the FBI and the army in
this matter. Whenever I mentioned the name of one particular individual
named Conrad, the man’s cigarette shook in his hand like the needle on a
polygraph machine. To see if this was a random event or something more
significant, I mentioned additional names to test his reactions; there were
none. Yet, on four separate occasions, when I mentioned Conrad, the
subject’s cigarette repeatedly shook. For me that was enough to verify
there was more to the relationship between the interviewee and Con-
rad than we knew. The shaking of the cigarette was a limbic reaction to a
threat. It was also an indication to me that this individual felt somehow
endangered by the revelation of that name; therefore he likely either had
knowledge of something nefarious or was directly involved in the crime.
During that initial interview with the subject, I did not know whether or
not he was actually involved in the crime because, frankly, I did not know
enough about the case. The only thing that spurred us to pursue the in-
vestigation and additional interviews was the fact that he had reacted to
one name with the “shaky hand” response. Perhaps but for that one be-
havior, he would have escaped justice. In the end, after many voluntary
interviews over a year, he admitted his involvement with Conrad in espio-
nage activities and eventually gave a full confession of his crimes.
their emotional state. In fact, if such a person suddenly ceases to tremble
for a moment, it may indicate a deliberate attempt to focus more deeply
on the particular subject just mentioned (Murray, 2007). Remember, it is
change in behavior that is most significant.
