Esmée Pascal is a character in DEXTER. She is a Haitian-American police officer who is considered a "real up-and-comer" after being shot in the line of duty.
Pascal remains Lieutenant of the department well over a month after the end of the case, earning the trust of the police officers and friendship of LaGuerta, but soon began to crack under pressure when she began experiencing personal problems with her fiancé Bertrand, suspecting him of adultery on little real evidence, which gradually casts doubt on her rationality. Her obsession becomes so strong that she uses department resources to investigate him; tracking his phone calls and has the forensics department do tests on his shirt, looking for a smell. Due to all of this, Captain Matthews returns control of the Homicide Division to LaGuerta, who was later revealed to be the one having an affair with Pascal's fiancé in the first place, as a way to get her old job back. She breaks it off as soon as her goal was accomplished.
