DC Endeavour Morse:
[looking at the evidence with Thursday, Jakes and Bright at the Police Station] He played a record. Tosca.

DS Peter Jakes:
[nodding] Tosca?

DC Endeavour Morse:
It's a penny dreadful of a plot. Filled with murder torture and suicide.

DS Peter Jakes:
Right up his street then.

DC Endeavour Morse:
At the climax, the heroine, Floria Tosca hurls herself from the battlements of the Castel Sant'Angelo.

Chief Superintendent Bright:
In summation then, apart from the method by which he means to dispose of this fifth and final victim, we know neither the where, the when nor the *whom* of it.

DS Peter Jakes:
If the killer's sticking to Morse's EGBDF pattern sir, it's got to be someone who's name begins with an F.

[Morse thinks for a moment, then realizes who the killer is]

DC Endeavour Morse:
It's Cronyn.

DS Peter Jakes:
What is?

DC Endeavour Morse:
[walking towards a blackboard, which has the names MASON GULL and KEITH MILLER? written in chalk on it] The murderer. It's Cronyn.

Chief Superintendent Bright:
[not convinced] I appreciate your work on this Morse, but I think you'll find...

DC Endeavour Morse:
Doctor Cronyn approached us, didn't he sir?

Chief Superintendent Bright:
Yes, but...

DC Endeavour Morse:
[confident] He's the one who's had us running around looking for this Keith Miller.

DI Fred Thursday:
[shocked] But Morse!

DC Endeavour Morse:
[confident] It's a joke sir. A blind. Keith Miller doesn't exist sir.

[Morse writes I'M THE KILLER on the blackboard]

DC Endeavour Morse:
[confident] Rearrange the letters of his name and you get... "I'm the killer". He's been toying us us, right from the beginning. Posing as Doctor Cronyn.

[flashbacks of Doctor Cronyn are seen]

Chief Superintendent Bright:
So who is he really?

DC Endeavour Morse:
[pointing to the other name on the blackboard] Mason Gull, sir.

Chief Superintendent Bright:
[impressed] Good grief!

DI Fred Thursday:
[confident] Then who's body did we find in Cronyn's consulting rooms?
