Xenophon Hellenica 5.4.7

[7] It was in this way, then, as some tell the story, that the polemarchs were killed, while others say that Melon and his followers came in as though they were revellers and killed them. After this Phillidas took three of his men and proceeded to the house of Leontiades and knocking at the door he said that he wished to give him a message from the polemarchs. Now it chanced that Leontiades had dined by himself and was still reclining on his couch after dinner, while his wife sat beside him, working with wool. And believing Phillidas trustworthy he bade him come in. When the party had entered, they killed Leontiades and frightened his wife into silence. And as they went out, they ordered that the door should remain shut; and they threatened that if they found it open, they would kill all who were in the house.
