Now, with a sense of timing that would see them booted off any drama course, its stars have delivered the denouement while everybody's back was turned.
They can hardly be blamed. They're a family of blue tits, whose life from hatching has been updated every three minutes on the web site of a Lake District primary school.
To the disappointment of their global audience, they chose a weekend to fly the nest in the grounds of Ambleside CE primary.
Ambleside's websitehas had 20,000 hits since the National Trust hooked up a webcam to the nest in February. Mark Robinson, the school's IT co-ordinator, said pupils had been disappointed to miss the big moment.
The venture was made possible after Year 6 pupils took second place in a National Trust competition earlier this year. They installed bird boxes around the school with their prize money.
The school hopes the birds will star in future Net dramas - but hopefully not on WormCam, the reception class's wormery.
