When an Oxford undergraduate meets by chance, a mysterious stranger, during a walking tour of France, he does not know that the unusual charismatic being he has made the acquaintance of, is in fact a disguised alien being, named Aleriel. Coming from the planet of peace, Venus, this space traveler claims to be visiting Earth for the first time. Thus begins an unusual interplanetary friendship, that takes our Oxford graduate on an amazing adventure, first into the war-torn streets of Paris, then across the English Channel, to busy London and finally on to tranquil Oxford. Aleriel then leaves his friend and explores many parts of the earth, to discover the state of mankind and humanity, before departing in his 'ether car' for the Moon, then returning to his home planet to report all his findings to advanced beings there.
