Ironside: Turks are quite familiar with Persian proverbs.
Ironside: On your way out, tell the reporters we expect to make an arrest within 50 hours.
Detective Keeley: Do we?
Ironside: No, but we've been telling them 48 hours for years.
(at the conclusion of his interrogation at his office)
Pierre Dupont: Now there isn't anything else, is there?
(opens door for team to leave and turns to Ironside)
Oh yes there is: you forgot to tell me not to leave town.
Ironside: Don't leave town!
(stopping Eve from staying with a victim)
Ironside: No, she'll be better off alone. The more you get into police work, Eve, the more you will know that every time you solve a case, some innocent person ends up behind a closed door crying. It's tough. You've got to be tougher.
The Leaf in the Forest
The title, according to Ironside, is from an ancient Persian proverb which he quotes in its entirety as:
The best hiding places are these:
for a book, a library
for a man, a city
for a leaf, a forest.
