Later on, he meets with Sarah she stays at his place for the night and they make love. Pogue tries throughout the day to figure out where the coin is but doesn't find any answers. Cornell shows up to his office to get Pogue's sworn statement but Pogue, mistaking Cornell for his landlord, gives him a check for rent. The next morning, Pogue has forgotten everything again.
The only clue the two have about the coin's location is one word Pogue said when Sarah gave it to him: "Baby". Sarah tells Pogue that she gave him the coin the morning before the explosion Pogue cannot remember. County Museum, which she in turn stole from him. Sarah also tells Pogue about a valuable coin Cornell stole from the L.A.

That night, Pogue meets Sarah at a fashion show she's modeling in. Sarah hired Pogue to protect her but was killed by a car bomb, the same bomb that caused his amnesia. On re-examining his files at the office, Pogue learns that Sarah was once Cornell's lover, who decided to testify against Cornell lest he kill her because of her knowledge of his illegal activities. Cornell offers Pogue a large sum of money to deny witnessing Cornell's involvement in the crime. Two henchmen take him from the party to meet Philip Cornell, the man Pogue is to testify against.

He realizes from a recording he made for himself the previous night (Sunday) – to keep himself in the know – that he's a private investigator in Los Angeles, and acquired the condition after being injured during a case. Maurice Pogue has retrograde amnesia, a form of amnesia that prevents him from remembering anything that happened to him the day before.
