The woman who died in the bedroom

Miss Lorraine, a young lecturer at a local university, is in love with her boyfriend, and it is said that they are getting married next month, but on this morning she is found dead in bed by the maid who comes into the house to clean.

When Inspector Roberto arrived, he went inside to see Lorraine in her pajamas and had been stabbed fatally in the chest. It has been speculated that the time of death was around 21:00 last night. After a police investigation, around 21:00 last night, two people came to see Miss Lorraine, one was her lover and the other was her student. When questioning the two suspicious elements, they both said that they had rang the doorbell, and when they saw that no one inside had agreed, they thought that Miss Lorraine was not at home and did not enter.

After listening to their story, Anthony remembered that Miss Caroline had a small peeping eye on the door, and he immediately knew who the real murderer was. So, can you guess who the real murderer is?
