Investigate (2)

Does this man have friends?

Despite being in astral form, Lawrence can touch nonliving objects. So he looked at Mr. Laurel's personal things. In his drawer, there's only a different set of ties and watches. 

But the second drawer and the last were locked. Lawrence looked around the room, but the key was nowhere to be found. 

"Meow!" Kevin stretched his body upward and used his meat paw pad to point at the first drawer. 

[The key is underneath the drawer!]

Lawrence crouched down, and indeed, two sets of keys were taped to the bottom of the first drawer. A common hideout, especially if you want to hide small things like keys. 

Lawrence took them off and opened the second drawer. It was filled with textbooks. 

Math exercises books. Lawrence looked at the cover and frowned. 

The name on the cover is Louise Nickel. Lawrence put the books down on the ground. There are four math exercises in total.
