It begins where all of it begins: a single ribbon of eggs strung through the warm shallows of Cattail Cove, rocking in water so still you could count the tadpoles by their shadows. There were dozens in that clutch. Only two of them matter to this case, and on the morning they hatched, not even their own mother could tell which was which.
She solved it the way mothers do — with a notch. One small nick pressed into the left fin of the calmer of the two, the one who surfaced without thrashing, the one who waited his turn at the algae. That was PeePoo. The notch is in the record now, exhibit-adjacent, because fourteen seasons later it is still the single cleanest way to tell the honest twin from the one who learned to imitate him.
Two tadpoles, one notch — and a face that would take fourteen seasons to become a crime scene.
They shared one lily pad. For a long while that was enough. Neighbors who lived along that stretch of the cove — and several have since sworn statements — describe two frogs so identical in face and so opposite in habit that the pad itself seemed to lean. PeePoo folded the cattails flat after every storm so the smaller creatures could find their way home. The other twin watched him do it. Watched, specifically. Not helped. Took, by more than one account, a kind of quiet inventory.
There is a version of this story the prosecution would prefer, in which two frogs are simply two frogs and any resemblance ends at the waterline. But the neighbors keep returning to the same detail without being asked: that PeePoo never once seemed aware he was being studied. He gave away his manners freely, the way he gave away everything, and somewhere three pads down a mirror-image was writing all of it down for a rainy day it fully intended to cause.
By the time the pad could no longer hold them both, the split was less a fight than a tide going out. One twin drifted toward the deep water on the far side of the cove — we are not, for reasons that will become clear, permitted to name that side. The other stayed exactly where he'd hatched, kept the notch, kept the cattails folded, and kept, above all, the better manners. He did not know he was keeping them for a trial.
Every frame job needs a face it can borrow. This is the chapter where the face was made — two of them, identical, from the same string of eggs in the same warm shallows — and where, if you were paying very close attention, you could already tell which twin would spend a season behind glass insisting the other one did it. He was right. It only took the swamp fourteen seasons to start listening.
