#### Whom we suspected to be the “mum” referenced. However, entering `DUCTF{emily_waters}` didn’t work, and we realised there was a middle name from the email:

#### Sending an email to that email address got us an out-of-office reply:
####
> Email to [email protected].
> Subject line: “Business inquiry: middle name”.
> Body: “Hi there! I love your cat Alexandros! Such a cutie. I have a business inquiry regarding a particular flag. Do you mind if I ask you what your middle name is?

> Email reply from [email protected].
> Subject line: “Out of Office from September 6th Re: Business inquiry: middle name”.
> Body: “Hello, I will be out of the office from Sunday, September 6th onward. If you need immediate assistance during my absence, that sounds like a you problem. Otherwise, I will probably respond to your emails as soon as possible if I return.
> Kind regards,
> Emily Theresa Waters.
