Why do my spokes keep breaking? - Bike wheel science.

[roubaixtuesday]

I was sat in the dining room when through the sliding door I heard a hissing, went into the conservatory to find the rear wheel slowly deflating. Bike hadn't moved for more than 30 hours (since I'd got home from work the previous morning) maybe another 100 yards of travel and it would have gone but it is weird when just sitting there the tube decides to (audibly) deflate.

That is properly weird! Where was the hole?
