To Sing a Song of Murder - S3-E20

The Three Virgins of Rome - S3-E7
Continuity mistake: When Alister Mundy's three friends are retrieving the paintings at the end, a small black dog appears, seemingly out of nowhere, and between takes is suddenly trotting along beside them. (00:44:50)
Flowers From Alexander - S3-E5
Continuity mistake: Sykes is drinking a beer when Nicholas knocks on the door, and he leaves the beer can on the balcony railing when he crosses to let Nicholas in. When they both walk out onto the balcony a moment later, the beer can has disappeared. (00:43:05)
Continuity mistake: When Botarelli gets up from the banquet table, a large orange, sitting beside his wine glass in close-up, disappears in the next, wider shot. (00:21:30)
Continuity mistake: Mona draws a heart in the dust on the bar and writes "Al + Mona" inside it. When we see a close-up it, however, the L is suddenly much larger than before, and the name "Mona" is written in smaller letters. (00:04:00)
Continuity mistake: Angela's limo picks up Mundy and drives down a tree-lined country road. But in the very next shot, the view out the back window is of a busy city street with nary a tree in sight. (00:13:00)
