The Poison within the Family — Peter Regan

After the daughter of a former employer goes missing, Alex Wade and Sky Lee begin a dangerous journey that rapidly descends into a seedy world of drugs, crime and murder. Whilst private investigations start in Manchester, evidence points toward answers that may be found in Malaga, Spain. What they eventually discover will not only test their detective skills, but also bring into question all they believed was true about people they thought they knew.
