The aptly named To touch a Rainbow sees David taken to the exquisite tomb of Aphrodite by the mysterious trio, but someone has followed them.
I loved this finale, a wonderful end to the great story, it takes on an almost fantasy turn here, I thought it had happened earlier, but it's saved for the final episode, which sees David finally learn all, including who killed his brother.
Stunning production values, the tomb looks amazing, opulent and rich, costume I know, but the team did a wonderful job here.
A fitting end to a special series. 9/10.
