While Anna sleeps peacefully, Tom's helping a cow give birth. After a hard night, he sneaks back at 5am little realising that he's observed by a suspicious Sarah.

It's Sunday and George and Claudie are late rising, arriving for their fry-up in matching black silk dressing gowns. Eyebrows are raised.

Tom's also receiving mysterious phone calls. Setting off to buy the papers he doesn't come back for almost three hours, meaning Anna has to run the kids' errands. She's worried, suspicious and angry. She tries to call and is shocked when a woman answers but quickly hangs up. Little does she realise that Tom is secretly locuming to fund his payments to an increasingly demanding Fiona.

The stress of the secrecy and extreme tiredness is making Tom grouchy. Then his woes are compounded when his father Jim drops by for an unexpected visit. Tom's childhood was not a happy one as his alcoholic father abused him and he's less than overjoyed to see Jim. "You destroyed my childhood" he accuses. Jim is dying and seeks reconciliation but no amount of apologising will sway his son.

Things come to a head when Tom gets his operation list confused and mistakenly castrates a prize pedigree stud dog. Its owner is far from happy and demonstrates his rage with his fists.

Meanwhile, Jim is forced to stop an angry Tom from attacking Fiona. It transpires that James is also paying a monthly allowance towards Theo's upbringing. Tom demands a paternity test.
