HE IS the watchman of The Gap. A former life insurance salesman who in 45 years has officially rescued about 160 people intent on jumping from the cliffs at Watsons Bay, mostly from Gap Park, opposite his home high on Old South Head Road. Unofficially, that figure is closer to 400.

Some, at his urging, quietly gathered their shoes and wallets, neatly laid out on the rocks, and followed him home for breakfast. Others, tragically, struggled as he grabbed at their clothes before they slipped over the edge.

Still others later sent tokens of thanks, a magnum of champagne or an anonymous drawing slipped into his letter box, labelling him ‘‘an angel walking among us’’.

Don Ritchie, 82, spends much of his time reading newspapers, books and scanning the glistening expanse of ocean laid out before him. His days of climbing fences are gone and he admits some relief that most visitors now carry mobile phones and are quick to contact the police if they see a lone figure standing too close to the edge, too deep in contemplation.
