Here’s the full solution to all the clues in Episode 6:

Clue 1: David Boreanz (the actor on the top left of the newspaper clipping) plays the character “Angel” in Buffy the Vampire Slayer and spin-off series Angel.

Clue 2: The exhibition advertised is at the Laing Gallery, which is in Newcastle.  The artist mentioned, Anthony Gormley, is the artist who designed the Angel of the North.

Clue 3: The main news story refers to Carville Power Station being reopened.  Carville Power Station is in Wallsend, near Newcastle.  The article mentions the power station could provide 25 MW of power: more than the 18 MW required by Moriarty’s EMP in episode 5.

Clue 4: The special offers at the bottom of the newspaper advertised Dan Brown books.  Dan Brown wrote a book called “Angels and Demons”.  Also advertised was a signed Alan Shearer shirt.  Alan Shearer played most of his career at Newcastle United, and a large Alan Shearer shirt was famously draped across the Angel of the North soon after its construction.

Clue 5: Click here to find the full crossword solution.  The full solution provides the number 1201533365.  If you visit the you will find a picture of the Angel of the North.

Clue 6: The first entry in the lonely hearts column refers to looking in maths books for clues.  In Holmes’s case notes he mentions using the Longman AQA GCSE Mathematics Middle Sets book as a clue.  Each pair of numbers in the lonely hearts column refers to a word in this book.  The first number is a page number and the second number is a word number.  So for example the first word is the 13th word on page 242.  The six words spell out WEAPON IN HEAVENLY IMAGE IN GATESHEAD.  A reference to the location of the Angel of the North.

Clue 7: The third lonely hearts advert is from Moriarty!  He asks Holmes to include the code 26435 in his text message when responding.  If you enter these digits in to a text message with predictive text messaging on it will spell out the word ANGEL.

Clue 8: The fourth lonely hearts advert is for an “Outdoorsy Type”.  This advert refers to the Angel of the North, which is constructed from steel and is 12 years old.
