Love and Death in London — Francine Pascal

Murder most foul…
Elizabeth and Jessica Wakefield are looking for trouble. Working as summer interns assigned the Scotland Yard beat for the London Journal, they're bored with all the petty cases they've been given. When a series of grisly murders breaks out, they decide to do some sleuthing on their own.
Elizabeth and Jessica discover that the murder victims look as if they've been attacked by a wild animal. Who â€" or what â€" could have committed such a beastly crime? The detectives are baffled, but the twins, led by Luke, the quiet boy who is quickly finding a place in Elizabeth's heart, have their own suspicions. Will they find the murderer, before â€" he or it â€" finds them?
Book one in this terrifying three-part miniseries … Jessica and Elizabeth have never been in so much danger!
