It's in His Kiss: The 2nd Epilogue (Bridgertons 7.5)

Oh. Dear. God.

What was she going to do? What was she going to do? She knew what she must do, but good God, how was she supposed to do it?

And what could she say? What could she possibly say to-

Forget that for now. Forget it because her mother was talking again and she was saying, “You could have bought me a necklace. And you could have hidden it. Just so that I could have found it, you could have hidden it. But you didn’t.”

There was so much love in her voice it made Isabella’s heart ache. And something about it seemed to sum up everything that her parents were. To themselves, to each other.

To their children.

And suddenly the moment was too personal to spy upon, even for her. She crept from the room, then ran to her own chamber, sagging into a chair just as soon as she closed the door.

Because she knew what her mother had been looking for for so very long.

It was sitting in the bottom drawer of her desk. And it was more than a necklace. It was an entire parure-a necklace, bracelet, and ring, a veritable shower of diamonds, each stone framed by two delicate aquamarines. Isabella had found them when she was ten, hidden in a small cavity behind one of the Turkish tiles in the nursery washroom. She should have said something about them. She knew that she should. But she hadn’t, and she wasn’t even sure why.

Maybe it was because she had found them. Maybe because she loved having a secret. Maybe it was because she hadn’t thought they belonged to anyone else, or indeed, that anyone even knew of their existence. Certainly she hadn’t thought that her mother had been searching for them for fifteen years.

Her mother!

Her mother was the last person anyone would imagine was keeping a secret. No one would think ill of Isabella for not thinking, when she’d discovered the diamonds-Oh, surely my mother must be looking for these and has chosen, for her own devious reasons, not to tell me about it.

Truly, when all was said and done, this was really her mother’s fault. If Hyacinth had told her that she was searching for jewels, Isabella would immediately have confessed. Or if not immediately, then soon enough to satisfy everyone’s conscience.

And now, speaking of consciences, hers was beating a nasty little tattoo in her chest. It was a most unpleasant-and unfamiliar-feeling.

It wasn’t that Isabella was the soul of sweetness and light, all sugary smiles and pious platitudes. Heavens, no, she avoided such girls like the plague. But by the same token, she rarely did anything that was likely to make her feel guilty afterward, if only because perhaps-and only perhaps-her notions of propriety and morality were ever-so-slightly flexible.

But now she had a lump in the pit of her stomach, a lump with peculiar talent for sending bile up her throat. Her hands were shaking, and she felt ill. Not feverish, not even aguish, just ill. With herself.

Letting out an uneven breath, Isabella rose to her feet and crossed the room to her desk, a delicate rococo piece her namesake great-grandmother had brought over from Italy. She’d put the jewels there three years back, when she’d finally moved out of the top-floor nursery. She’d discovered a secret compartment at the back of the bottom drawer. This hadn’t particularly surprised her; there seemed to be an unc

ommon number of secret compartments in the furniture at Clair House, much of which had been imported from Italy. But it was a boon and rather convenient, and so one day, when her family was off at some ton function they had deemed Isabella too young to attend, she’d sneaked back up to the nursery, retrieved the jewels from their hiding place behind the tile (which she had rather resourcefully plastered back up), and moved them to her desk.

They’d remained there ever since, except for the odd occasion when Isabella took them out and tried them on, thinking how nice they would look with her new gown, but how was she to explain their existence to her parents?

Now it seemed that no explanation would have been necessary. Or perhaps just a different sort of explanation.

A very different sort.

Settling into the desk chair, Isabella leaned down and retrieved the jewels from the secret compartment. They were still in the same corded velvet bag in which she’d found them. She slid them free, letting them pool luxuriously on the desktop. She didn’t know much about jewels, but surely these had to be of the finest quality. They caught the sunlight with an indescribable magic, almost as if each stone could somehow capture the light and then send it showering off in every direction.

Isabella didn’t like to think herself greedy or materialistic, but in the presence of such treasure, she understood how diamonds could make a man go a little bit mad. Or why women longed so desperately for one more piece, one more stone that was bigger, more finely cut than the last.

But these did not belong to her. Maybe they belonged to no one. But if anyone had a right to them, it was most definitely her mother. Isabella didn’t know how or why Hyacinth knew of their existence, but that didn’t seem to matter. Her mother had some sort of connection to the jewels, some sort of important knowledge. And if they belonged to anyone, they belonged to her.

Reluctantly, Isabella slid them back into the bag and tightened the gold cord so that none of the pieces could slip out. She knew what she had to do now. She knew exactly what she had to do.

But after that…

The torture would be in the waiting.

One year later.

It had been two months since Hyacinth had last searched for the jewels, but Gareth was busy with some sort of estate matter, and she had no good books to read, and, well, she just felt…itchy.

This happened from time to time. She’d go months without searching, weeks and days without even thinking about the diamonds, and then something would happen to remind her, to start her wondering, and there she was again-obsessed and frustrated, sneaking about the house so that no one would realize what she was up to.
