But killing her roommate?
She swears it didnt happen.
Ive made some major mistakes, but theres one thing I didnt do; I didnt kill Molly Ryan.
She was my friend.
relax a little bit.
Is it all just a game for Grace?
Guilt-O-Meter reading:7 out of 10.
Lets be cautiously optimistic and assume the latter for now.

Major jump for the new mystery.
Detective Pike
Just a detective doing detective-y things.

Guilt-O-Meter reading:Still nil.
She says she believes him, but the sudden arrival of sirens says otherwise.
James
Dirtbags still dirty.
So, its hardly surprising hell shell out thousands of quid to whoevers holding it hostage.
The guys the human version of feces.
Fancy human feces, but still.
Guilt-O-Meter reading:Off the charts.
Guilt-O-Meter reading:Lets go with 2 this time.
Professor Jeffrey Lindley Beatrice Lindley
Welp.
No, Bea admits.
I dont suppose killing you will help either.
