Sometimes the balm of time does not heal, especially when it comes to missing children.

There are literally hundreds of faces — most of them smiling.

Black and white, colour and frozen forever in time.

And missing.

I thought about those faces this week as I watched The Disappearance of Madeleine McCann on Netflix.

Maddie McCann was just 3 years old when she disappeared.

Maddie, as she was called by the British press, was a 3-year-old cutie who vanished without a trace from her parent’s holiday villa in Portugal in 2007.

One of the greatest dragnets in European history turned up nada. Threads so slender as to what really happened they couldn’t sew a button.

And the deeper you go into Maddie’s disappearance — lone pedo? sex traffickers? A childless couple? Tragic accident? — the less any of it makes sense.

“It was an extremely difficult investigation,” former detective Keith Daniels said, adding that the probe was hampered because the McCanns were a foreign family.
