Would you trade your sister for a telescope? Another hilarious adventure starring Bostock and Harris.

On the night that Piggot’s Comet will appear over Brighton, the town plan to honour it with music and dancing. Harris, however, has other ideas. Being scientifically minded, he thinks only of observing the comet in detail. He persuades his good friend Bostock to part with his father’s telescope in exchange for the affections of Harris’s sister, Mary. Unfortunately, as Mary does not care for Bostock, Harris is forced to apply his powerful mind to the problems of courtship and love.
