Sammy Silke's plan to kill and replace the Kingpin went off without a hitch. Well, unless you count the Kingpin's wife coming back to town, killing every collaborator in the plan, getting cut off from family support, and finding yourself looking for a safe haven with no friends and an unwillingness to tell the F.B.I. the details of your mob family's operation. If those count, then there were a few hitches. Sammy's going to need to give the F.B.I. some monumental information to keep himself out of prison.
