Montillo traces some of the scientific antecedents of the tale -- Galvani and Volta, etc. The heyday of the resurrection men. And the tangled web of Shelleys Wollestonecrafts Byrons Polidoris and others that went into the creation of Frankenstein. On the whole, I found it a bit disappointing in that it doesn't strongly connect the scientific threads with what Mary Shelley was writing about. In general terms, yes, but nothing direct and concrete, no doubt because Shelley didn't leave any concrete details of the sort behind. But at least there was enough bed-hopping among husbands and wives, brothers and sisters, to keep things interesting.
