Martha Hanson is Agent Gaad's secretary, Clark's (Phlip's alias for her alone) informant and later Clark's wife. Philip used his relationship with Martha to keep an eye on things at Gaad's office. She was reluctant to perform some tasks, though she would eventually agree, though other times (through Philip's manipulation) would exceed his requests and provide more information than he thought she could obtain. When Martha was ready to stop doing things for him, Philip further manipulated her by asking her to marry him, which he did. After Stan and Gaad discovered a bug planted in Gaad's own office that Martha left there, Philp was forced to reveal that he was not who he said he was, he intimated that he was a spy and promised her he would protect her. He even admitted to killing another man for her.
