Primavera Blackstone has found a hard-earned contentment in a small Spanish village by the sea. A fiercely protective single mother, she doesn't appreciate an offer of marriage. Nor does she welcome the arrival of a blast from her murky Scottish past, retired cop Ricky Ross, now a private detective and working for Jack Weighley, millionaire owner of a budget airline. Jack is a powerful, persuasive man with deep pockets, someone you don't say 'no' to without considering the consequences. So Primavera teams up with Ricky to investigate a series of mystery assaults on Jack's aircraft. Are they mere acts of vandalism, or the sinister work of Catalan extremists? When Ricky's car is fire-bombed and he narrowly escapes with his life, more questions arise.
