The man had recently been rebuffing her attempts for a divorce. Perhaps he will reconsider his stance at this point. To say the least, he is suing her for attempted murder.
The wife, meanwhile, was lucky to visit the hospital, as it was discovered that there was enough poison in her vagina to kill them both. She subsequently was treated to avoid being done in herself by her cunning plot.
It should be noted that this is an especially bad way to try to kill somebody, unless you intend to kill off yourself as well, as the vagina could be said to be a “second mouth” in that it absorbs what is put into it. The woman could very well have lost her life, and was saved, in a manner, by her concerned husband.
