What can I do at the Solicitor's Office?

You can chat with your alien buddy, for one.

You can also play dress up.

Or if you're not in the mood to try on other people's wigs, you can tidy up instead.

Put the WIG on the wig stand on the drawer table.

Take the "legal contract" out of Caesar's head (that sounded weird).

It's a REBUS again. Try and sound out the images, see what you make of them.

All images represent items of the same group.

They're alphabet letters.

Bee, Why, Jay, You, Oh, Arr.

Or in other words: B, Y, J, U, O, R.

Now what do these letters mean?

Have a closer look at the solicitor's library.

The books also have letters on their spines.

Tap one tome and then another so that they can switch places.

Switch B with Y, J with U, and O with R.

Take both items out of the secret compartment in the spine of tome X.

Don't forget to look in the open file DRAWER, too!
