London (CNN) It's more than a week in and questions are still swirling over how and why a former Russian spy and his daughter were poisoned in the cathedral city of Salisbury in southern England. Russia's Foreign Ministry described May's strongly-worded statement as a "circus show" and the latest in a series of "fairy tales". While Monday's developments are likely to plunge relations between the UK and Russia to a new low, a number of key questions remain unanswered. Does that mean he was heavily exposed at the bench, say from trying to resuscitate the pair? And then 24 hours after that they stepped forwards to say they knew the "specific nerve agent" it was.
