Piecing together the parts introduced in Chapter 1 results in a photofit of a presumed, but highly elusive phenomenon. Like a biologist we are pursuing a (potential) new species, knowing that the jungle we are about to enter harbours an exciting breed, but we are not sure whether it walks or flies, preys on cadavers or forages on clover, whether it has two heads and six legs or slithers through the long grass like a snake. It is not even clear whether that species is a fascinating mirage like the Terrible Snowman or the Loch Ness monster; of if it is just a workaday bug or toad, of interest to zoologists only.
