Jessica Fletcher and Our New PM

What links the baby pounding the Mercedes Prima portable in the top image and the lady at the Royal KMM standard in the bottom?
One is the new Prime Minister of Australia, former journalist Malcolm Bligh Turnbull (1954-), and the other is the fictional mystery novel writer Jessica Fletcher, as played by British-born American actress Dame Angela Lansbury (1925-) in Murder, She Wrote.
Turnbull and Lansbury are cousins, albeit distant ones. Their respective grandfathers were actually first cousins.
