Page "Farewell, My Lovely" Paragraph 4

Marlowe visits Mrs. Grayle but she is more interested in coming on to him than finding her necklace.

He then visits Amthor in his office, and probes for his connection to Marriott and the drugs.

Amthor dismisses his questions, then has him assaulted and thrown out by two crooked policemen, who lock him up in a private hospital.

He escapes, but on the way out sees Malloy sitting freely in another room.

He discusses the case with Anne Riordan and the police, who are annoyed at his continued involvement.

They suspect Marriott of blackmailing wealthy women, in league with Amthor.

Marriott hid the cards inside the drugs to implicate Amthor if he were found dead, but they doubt Amthor is the killer.

Marlowe investigates the crooked cops and learns they were essentially unwitting dupes for Amthor, who thought Marlowe was trying to blackmail him.

The hospital is an unrelated front for dope peddling and hiding fugitives.
