Archie faces obstacles as he tries to open his Wildlife Centre. Irene's having trouble coping with all the cooking and cleaning so when teenager Esme turns up looking for casual work, it seems too good to be true. Archie is distrustful of her, but she's a good worker and Lexie's glad she hired her.Archie's too preoccupied with the grand opening of the Wildlife Centre to pay much attention to anything else. If the opening isn't a success, Archie fears the estate will be unable to pay off the death duties they incurred after Hector's demise.He has applied for a grant from a wildlife charity, but the representative who turns up is Professor Isobel Hogg - a wildlife expert, his godmother and a sworn enemy of Molly.
