My grandfather's job had meant the family moved from Thursley to Godalming, presumably in the summer. Fifty years on, I visited the church with Mum, and saw the tiny graves in the churchyard.

(And led to an indignant rebuttal the following week at the idea that London slum children might have caused the outbreak)
But "only" two children died. This is an outbreak, rather than an epidemic. How do you spot such things?
