Afterwards I felt bad about what I had said and how I had said it, and decided as penance I would force myself to go out with Mary and Colonel Birch again, to blunt the sharp tongues of Lyme. Mary accepted my gesture easily, for love made her forgiving.

That was why I was with them out by Black Ven when they at last found the ichthyosaurus Colonel Birch was so keen to add to his collection. I was finding very little that day, for I was distracted by the behaviour of Mary and Colonel Birch, who were more openly affectionate than they had been weeks before: touching an arm to get the other’s attention, whispering together, smiling at each other. For an awful moment I wondered if Mary had succumbed completely to him. But then I reasoned that if she had, she would not go to such lengths to seem accidentally to touch his arm. I did not know of married couples who caressed each other so eagerly. They did not need to.

I was pondering this when I saw Mary pause on a ledge and look down, the way I’d seen her do hundreds of times. It was the quality of her stillness that told me she’d found something.

Colonel Birch went on a few paces, then stopped himself and came back. “What is it, Mary? Have you seen something?”

Mary hesitated. Perhaps if she’d realised I was watching she wouldn’t have done what she did next. “No, sir,” she said. “Nothing. I just-” She let slip her hammer, which fell with a clang to rest. “Sorry, sir, I’ve come over a little dizzy. It must be the sun. Could you fetch my hammer for me?”

“Of course.” Colonel Birch bent to pick it up, froze, then dropped to his knees. He glanced up at Mary, as if trying to read her face.

“Have you found something, sir?”

“Do you know, I think I have, Mary!”

“That’s a dorsal vertebra, isn’t it? See, sir, if you measure it you can tell how long your creature is. For every inch in diameter the ichie is five feet in length. This is about an inch and a half in diameter, so the creature would be about eight feet long. Look round and see if you can uncover other parts of it in the ledge. Here, use my hammer.”

She was giving the ichthyosaurus to him, and he knew it. I turned away, disgusted. While they excitedly traced the outline of the creature in the ledge, I busied myself knocking open random rocks, just to keep myself busy, until they called to me to come and see Colonel Birch’s find. I could barely look at it, which was a shame, for it was perhaps the finest ichthyosaurus Mary ever found, and it is always an impressive sight to see one embedded in its natural environment before it is cut out of the stone. However, I had to put on a civil face and congratulate him. “Well done, Colonel Birch,” I said. “It will make a fascinating addition to your collection.” I allowed the slightest hint of sarcasm into my voice, but it was lost on them both, for Colonel Birch had taken Mary into his arms and was swinging her about as if they were at an Assembly Rooms ball.

They spent the next two weeks having the Day brothers dig out the ichthyosaurus, and cleaning it back at the workshop, with Mary doing the delicate work to make it presentable. She worked so hard on it her eyes went red. I did not visit while she prepared it, for I did not want to be caught in the close quarters of the workshop with Colonel Birch. Indeed, I avoided him as best I could. Not well enough, however.

One afternoon Margaret convinced me to play cards at the Assembly Rooms. I did not go often, for it was full of young ladies and men courting, and mothers watching the proceedings. The select friends I had made in Lyme were of a more cerebral nature, like young Henry De La Beche or Doctor Carpenter and his wife. We usually met at one another’s houses rather than at the Assembly Rooms. But Margaret wanted a partner, and insisted.

In the middle of a game Colonel Birch walked in. Of course I noticed him immediately, and he me-he caught my eye before I could look away, and came straight over. Trapped by my cards, I responded to his greeting with as little expression as possible, though that did not stop him from standing over me and chatting with onlookers. The other players looked at me with amused surprise, and I began to play badly. As soon as I was able I feigned a headache and got up from the table. I had hoped Colonel Birch would take my place, but instead he followed me to the bay window, where we both looked out to sea. A ship was sailing past, about to dock at the Cobb.

“That is the Unity,” Colonel Birch said. “I am having the ichthyosaurus shipped on it to London when it leaves tomorrow.”

Despite not wanting to engage in conversation, I could not help myself. “Has Mary done with her work on the specimen, then?”

“It’s set in its frame, and just this afternoon she put a plaster skim around it to finish it. It should be dry later, and she’ll pack it up.”

“But you are not going on the Unity yourself?” I was not sure if I wanted him to stay or go, but I had to know.

“I will go up by coach, stopping first at Bath and Oxford to see friends.”

“Now that you have what you came for, I suppose there is no reason to stay on.” Hard as I tried to keep it steady, my voice wavered. I did not add that his haste to depart after securing his treasure was in poor taste. Instead I kept my eyes on the waves that chopped and swayed under the window, for the tide was high. I could feel Colonel Birch’s eyes on me, but I did not turn to face him. My cheeks were flushed.

“I have very much enjoyed our conversations, Miss Philpot,” he said. “I shall miss them.”

I turned then and looked at him direct.

“Your eyes are very dark today,” he added. “Dark and honest.”

“I am going to go home now,” I replied, as if he had asked. “No, don’t accompany me, Colonel Birch. I do not want you to.” I turned. It seemed the entire room was watching us. I went over to fetch my sister, and was truly relieved that he did not follow.

I believe the months after Colonel Birch’s departure were the hardest ever for the Annings-even harder than after Richard Anning died, for at least then they had the sympathy of the town. Now people simply thought they had brought on their misery.

I first truly understood how much damage Colonel Birch had done to Mary’s reputation when, not long after, I heard for myself what people were saying. I went into the baker’s one day-Bessy had forgotten to, but refused to go down the hill once more. As I entered I overheard the wife of the baker-who was an Anning himself, and a distant cousin of Mary’s-say to a customer, “She spent every day on the beach with that gentleman. Let him take care of her.” She chuckled crudely, but stopped when she saw me. Even though no names had been mentioned, I knew whom she was referring to: It was clear from the defiant tilt of her chin, as if she were daring me to chide her for being so judgemental and ungenerous.

I didn’t rise to the challenge. It would have been like trying to damn a flood. Instead I fingered a loaf of bread, raised my eyebrows, and said in a ringing voice, “I don’t really need stale bread today. I’ll come another day when I do.” It gave me only momentary satisfaction, though-for Simeon Anning was the only baker in Lyme, and we would have to continue to buy from his wife if we wanted bread we could actually eat, as opposed to Bessy’s brick-like attempts. Besides, my words were weak and petty, and did little to help Mary. I left the shop red-faced, and it was made worse by the laughter that followed me. I wondered if I would ever be able to speak up for myself without feeling an idiot.

While Molly and Joseph Anning suffered materially that winter, with many days of weak soup and weaker fires, Mary barely noticed how little she was eating or the chilblains on her hands and feet. She was suffering inside.

She still came to Morley Cottage, but preferred to visit Margaret, for my sister could provide her with the empathy that Louise and I lacked. We had not lost a man the way Mary and Margaret had, and it was not in our natures to dissemble. Not that Mary felt she had lost Colonel Birch at that point. For a long time she was hopeful, and simply missed him and the constant presence he had been in her life all summer. She wanted to talk about him with someone who knew him and approved of him, or at least didn’t express the sour criticism of his character that I had. Margaret had met Colonel Birch several times at the Assembly Rooms, had played cards with him and even danced with him twice. While I worked on my fossils at the dining room table, I could hear Mary with Margaret next door, making her describe again and again the dances, what Colonel Birch had worn, what his gait and touch had been like, what they had chatted about as they went through their motions. Then she wanted to know about the cards, what they had played and whether he won or lost, and what he had said. Margaret had not noticed such details, for Colonel Birch had not been a memorable companion to her. His vanity and confidence were too much even for Margaret. However, for Mary she made up details to add to the little she did remember, until a fulsome picture emerged of Colonel Birch in his leisure moments. Mary drank in every detail, to store and pore over later.
