The South Bridge Enigma

It is 1786, and Dr Erasmus Darwin of Lichfield receives a letter from an old friend at Edinburgh University. Something strange and perhaps uncanny seems to be emerging as work progresses on the new South Bridge in that city, and the old friend would appreciate new eyes on the problem.

As servants of the Lunar Society, you are despatched to investigate, and to carry Enlightenment into darkness. Dr Darwin trusts that your skills will overcome any wild and superstitious nonsense, after all.
