Eighteen year old Kate married Edward Tyson - a man old enough to be her father. He was in ill health at the time, but she thought she loved him. Her friends were getting married and having children so she felt left out. Three years later he died leaving her an extremely wealthy widow.
Seeing a personal advert in the local newspaper she believes it to be her mother trying to make contact with her. She only discovered that she had been adopted when she was in her late teens. She manages to get a job at the firm (Roberts Construction) her mother works for, and there meets a man from her past. Matt Roberts was someone she had a crush on. She ends up working for Matt and finally decides to confront her mother with her true identity. Delia Roberts explains how it was she had to have Kate adopted, but Kate doesn’t find her a particularly approachable person. Delia proves to be rather devious and manipulative.
Kate enjoys working for Matt. Delia is Matt’s stepmother and the two of them do not hit it off. Matt’s father had died recently leaving a strange will. He added a clause soon after his latest marriage to the effect if Delia had a child he or she could inherit the business. Kate wants nothing to do with it and tries to tell Matt but he won’t listen. Eventually Kate learns that Delia is her aunt not her mother and realises she has been lead astray so Delia could take over Roberts Construction. She flies out to Austria to meet her mother and then on to see Matt who is on holiday in Italy. Matt doesn’t make it easy for Kate to put matters right, but after various problems get resolved, they enjoy a passionate time together.
Kate is in seventh heaven until Carol (his previous secretary) arrives and she overhears her say that she is pregnant. Putting two and two together, she rushes away and takes a holiday in the Lake District. Matt eventually finds her and explains that he isn’t the father. While they are again resolving their differences, a problem arises at work and Matt has to rush back. Delia is at the root of it once again, and it takes a little sorting out, but eventually they set a date for the wedding.
