Episode 24. - Do you approve of my telescope? - It is most elegant. - I use it to keep an eye out for mermaids. Here. I'm delighted you dropped in. It was time we met. The best brandy in Dorset. I keep it for visitors from London who share a taste for the good life. - Your good health, Doctor. - Yours. Care for a cheroot? - Thank you. - I understand you're, er... a scientist. A seeker after fossils. - Palaeontology is my interest. I gather it is not yours. - When we know more of the living, it will be time to pursue the dead. - Yes, I was introduced the other day to a specimen of the local flora that rather inclines me to agree with you. A very strange case, as I understand it. Her name is Woodruff. - Ah, yes. Poor "Tragedy". I tell you something. We know more about your fossils on the beach than we do about that girl's mind. A German doctor called Hartmann has divided melancholia into various types. One he calls "natural", by which he means that one is born with a sad temperament. Another he calls "occasional" by which he means springing from an occasion. And the third class he calls "obscure melancholia" by which he really means, poor man, he doesn't know what the devil caused it. - But she had an occasion, did she not? - Oh, come now. Is she the first young woman to be jilted? No, no. She belongs to the third class: Obscure melancholia. Listen to me. I'll tell you, in the strictest confidence. I was called in to see her, oh, ten months ago. She was working as a seamstress, living by herself. Well, hardly living. Weeping without reason, unable to sleep, unable to talk. Melancholia as plain as the pox. I could see there was only one cure. To get her away from this place. But no, she wouldn't have it. She goes to a house that she knows is a living misery to a mistress that sees no difference between a servant and a slave. And she will not be moved. - But it's... incomprehensible. - Not at all. Hartmann has something very interesting to say about one of his patients. "It was as if her torture had become her delight." - And she has confided the true state of her mind to no one? - She has not. - But if she did? I mean, if she could bring herself to speak? - She would be cured. But she does not want to be cured.
