'Why? Does he say he did? Did the careless young fool lose the baby? Is he suspected of any kind of unprofessional conduct? What the devil is all this?'
'It concerns a possible charge of murder.'
'You can't convict a medical man of murder, even if he kills mother and child.'
'If you would be kind enough to look up your files? I assure you that it is of the utmost importance. Doctor Tassall is not suspected of killing Mrs Collins, nor her baby. It must be established, however, for his sake, that he did visit Mrs Collins late in the evening of last Saturday fortnight when he was called out from a birthday party at Hill Manor House.'
'What did you mean about a charge of murder? Young Tassall is a butterfly and a jackanapes, a trifler with young women's affections, a parasite and an arbutus, but he wouldn't murder anyone except in the course of duty and that, as I've already asserted, can't be held against him.'
'The murder of a young woman with whose affections he had trifled could be held against him,' I pointed out, picking up my cue, 'so the sooner you provide him with an alibi the better.'
'God bless my soul!' he said. 'I suppose you're serious?'
'I am officially concerned with the case as the accredited representative of the Home Office, because I am its consultant psychiatrist.'
'Oh? One of those...'
'Quacks?'
'No, no, of course not. I-let me see. Did the maid bring me your card? Yes, yes, here it is. Dear me! Oh, dear, dear me! Yes, of course, of course. And you want to consult our files. What was that date again?' I gave it to him. He had no filing cabinet, so he pulled out various drawers in a large desk and groped and fumbled among the miscellaneous contents, muttering to himself as he threw some of them on to the floor, 'List! List! There's a list of patients somewhere, I know there is! Ah!' he exclaimed at last.
Apparently he had found what he was looking for. He produced out of the miscellany a set of handwritten papers pinned together at the top left-hand corner, handed it to me and said,
'Look for yourself. I don't remember the name of Collins, now I come to think of it. Don't believe there's a family called Collins on our books.'
To cut the story short, Sir Walter, there was not. I left Doctor Matters after thanking him and apologising for cutting into his rest-time and rang up the inspector from a public call-box in the town. I told him of my researches and suggested that a call on Doctor Tassall might yield some information.
'Yes,' said the inspector, 'we're keeping him in mind. Looks as though his alibi has gone bust. We would have followed it up ourselves, the way you have done, if we could have shown he had any motive for killing Mr Ward, or any reason to have known there was a ready-dug grave in that cottage. You see, we are proceeding on the assumption that whoever killed the girl killed Ward.'
This argument had considerable force, for we had agreed that the strong probability was that the same person or persons had committed both murders and that the connexion with Hill House was too obvious to be ignored.
I then returned to Doctor Matters' house.
'I think I should warn you,' I said, 'to expect a visit from the police.' This time the old gentleman was uneasy, not belligerent.
'That boy!' he exclaimed. 'A young rascal! A scallywag! A flibbertigibbet! Yes, and more. But he's well qualified, madam, good at his job. Takes a lot of work off my shoulders. Popular with the patients. No murderer, madam, I assure you.'
'Yours, judging from the list of patients you allowed me to examine, is not a large practice, I believe, Doctor.'
'A country practice only, madam, but quite large enough for me, and, in any case, I admit it is picking up since young Tassall joined me.'
'I am surprised that so restless and talented a young man, if one may so interpret your description of him, is not more inclined to work in the metropolis.'
'He had quarrelled with his godfather, who had subsidised him for some years while he was studying for his qualifications. Something about jilting a girl whom Lord Kirkdale thought a suitable match for him. Took up with the Kempson granddaughter and had his allowance withdrawn. Couldn't afford his own practice. Glad to earn a pittance from me without having to buy himself in. No expectations, you know. Irresponsible young fellow.'
'And glad to be near Amabel Kempson-Conyers at such times as she came to visit her grandmother,' I thought, 'but perhaps not where his patients are irresponsible concerned.'
Well, since my last letter, in which you learned that young Doctor Tassall appears to have no alibi for the time and date of the murders, I have continued my borrowings and have come up with another gradu diverso, via una. In other words, our other chief suspects also cannot produce acceptable alibis. Neither the police nor I have seriously suspected Mrs Kempson or Mrs Conyers unless either of them had a male accomplice, since we hardly think that the interment of Mr Ward, even though he appears to have dug his own grave, was the work of a woman, nor is the murderer's method of dispatching his victims a likely one for a female to have employed. This I think I have already mentioned. In any case, I am not concerning myself at the moment with the death of Mr Ward.
Mr Conyers, I suppose, must remain on our list, since his only alibi
