A Double-Edged Sword
They dropped the paintings off at a shipping store and Will arranged for them to be sent to a storage unit in London. After that he sold his car to a used car lot without haggling because he wanted it over with and they finally made their way to the airport in a taxi.
Hazel held her breath when their IDs were checked because she was certain they would get called out on it but the woman behind the counter who checked in their bags was utterly unsuspicious.
She noticed that Will didn't speak during the entire transaction. Probably to hide the fact that he didn't sound British. He simply nodded and did what the woman said without a word.
This would be the most difficult part. Going by a fake name would be hard but completely changing the way she spoke would be much harder.
