'Aristocrat to avoid: awful cad with allure regularly lacking' (7)
I've got Dracula but the parsing isn't making entire sense. Cad is part of the answer but 'allure regularly lacking' doesn't quite work - neither 'alr' or 'lue' complete the answer. Thanks in advance.
the only way for it to work is if "regularly lacking" means lacking every third letter, thus leaving "al ur", which is what you require for the anagram
