Episode 11 (3x11)

:

A claw hammer recovered from a bin and contaminated with the DNA of both victim and killer is the final piece of the puzzle in a complex murder investigation. When the body of a woman is found, police speak to her lodger and become increasingly suspicious of his lies and strange behaviour, including the suggestion he has been tampering with her medication. Also today, the positive identification of a burglar who photographed himself at the crime scene leads police straight to his door.
