"A Traitor Stalks Among Us!" Part 1 of 3. Wanda has found another lead in the search for her missing brother. In hopes of finding Pietro, four avengers explore an underground tunnel in Manhattan! But something strange is going on beneath the streets...and the Black Panther, Scarlet Witch, Iron Man, and Hawkeye suddenly begin fighting one another! Could an old foe from long ago be manipulating the Avengers? Or maybe a super-villain of more recent vintage? Perhaps the answer is both! Meanwhile at Avengers Mansion, the Vision continues to ponder the Grim Reaper's offer to inhabit Simon Williams' comatose body. Captain America attempts to counsel the synthezoid avenger, but is interrupted by Rick Jones' barging into the mansion! Upon seeing Rick, the shield-slinger suffers a flashback to a battle vs. Hydra several months ago (in Captain America 113)! Very strange indeed! Cameo appearances by Captain Marvel and the Grim Reaper. (Note: The Space Phantom previously appeared way back in Avengers (1st series) 2.)
