Sherlock Holmes doesn't believe in luck. He doesn't believe in fate, favour, karma, or any of the other unscientific concepts people employ for making sense of fortunes both good and ill.
But…
Seven billion, ninety four million, five hundred and fourteen thousand, six hundred and seventy eight.
What are the chances that a very singular consulting detective, mean-mouthed and prickly, brilliant and vain, should meet one man hidden in so many? What are the chances that in a population so vast there would be a doctor, a soldier, a friend who, over time would take the time to help Sherlock, teach him, to love him?
What are the chances that this small man would need Sherlock's big hands to soothe away nightmares? That between short wriggly toes long fingers would perfectly fit?
What are the chances that the two of them would build a life together, watch telly, drink tea, talk long of thing petty and profound?
What are the chances that in a world of seven billion human beings Sherlock should meet John and in each other they would find contentment and peace, passion and love?
What are the chances?
One in one
For though Sherlock Holmes doesn't believe in fate or karma or luck or even prayer, he with all his heart believes this: There is no time, no world, no place in which he would not have met John Watson. Without even knowing they were looking, Sherlock knows they would have found each other.
No matter when or where or how…they would have found each other.
