Typo....Steyn nails it.
Intelligence is fine but the willingness to employ it and act upon what is uncovered is the most important:
Luca, I am worried about this man
Sollozzo. Find out what you can,
through the Tattaglias. Let them
believe you could be tempted away
from the Corleone Family, if the
right offer was made. Learn what
he has under his fingernails...
any idea come to mind about what the Godfather had in store for them if Luca had found anything out?
