Daredevil #178 (1982)

Elektra Natchios returns to her apartment one night, only to be attacked by a bunch of armed men. She easily defeats them and finds a note from the Kingpin, stating that if she survived the attack she is as capable an assassin as he surmised, and invites her to meet with him.

The next morning, Daredevil sprints across the city to resume his civilian guise of Matt Murdock, to meet with a young man named Sheldon who has checks that will implicate mayoral candidate Randolph Cherryh as being in the pocket of the Kingpin of Crime. Meeting with Sheldon with Foggy and Daily Bugle publisher J. Jonah Jameson, their private meeting is interrupted by some of the Kingpin's men, who wish to "talk" to Sheldon. In spite of Matt's best efforts in his civilian guise and as Daredevil, Sheldon bolts out of the office and manages to escape. Daredevil is at least able to prevent him from being assassinated.
