Hetti, who played Lucy in the BBC One soap, doesn't know who killed her character but has been wondering if she even had a murderer at all.
Speaking to Radio Times, the actress admitted that she has, like the rest of the nation, been attempting to come up with the answer to soap's biggest question!
Hetti said: "Part of me thinks it would give the public a shock if it turned out that Lucy committed suicide. Who killed Lucy? Lucy!"
The 'Who Killed Lucy?' storyline has been rumbling on in EastEnders since last summer, when the character's body was found dead on the common.
All viewers know is that she suffered a head injury and, so far, there are a whopping 19 suspects in the frame!
Fans haven't got long to wait though, as the killer will be unveiled during EastEnders' forthcoming 30th Anniversary week.
To celebrate the milestone, the cast will be filming live scenes and many old faces will be returning to Albert Square, including Jo Joyner (Tanya Branning), Barbara Windsor (Peggy Mitchell) and John Partridge (Christian Clarke).
Bosses have also released a creepy trailer to promote the Anniversary episodes, in which Lucy Beale makes a haunting return to Walford by floating above the Queen Vic.
The EastEnders Anniversary kicks off on 16 February with a special 30-minute live episode. All other episodes aired that week will feature live elements too.
We. Can't. Wait.
