chunk: After receiving treatment at Malvern himself, Darwin makes a pilgrimage to the hotel where Annie died. The journey marks a change in him; upon his return home, he is able to reconnect with his wife, and they speak to each other for the first time of their fears and grief over Annie's death. They specifically speak about the possibility that Annie died because she was genetically weak, as Darwin and Emma are closely related cousins. Their renewed devotion restores Darwin's health, and he is able to resume his work, as it also restores Emma's faith in their marriage, and she regains her strength to support his controversial work. Darwin decides that Emma must make the decision about publishing his work. After reading the manuscript, she quietly returns it to him, having addressed the package to John Murray publishers in London. Emma accepts that she is an "accomplice" now, but hopes that God will forgive them both.
