Sloan knew that. Sooner or later professional pride would rear its ugly head and an opinion would be offered.
âWell, if thereâs a fragment of femur shaft you can sometimes have a view of the sex of the deceased.â He grinned. âAlthough, unless itâs in the region of the linea aspera, I must say itâs pretty nearly as difficult as doing day-old chicks.â
Sloan said austerely, âThe sex does not present any difficulty.â
âAnd,â continued the doctor, âif there are clear remains of two bones of which homo sapiens has only oneâthe sacrum of the Atlas vertebra, for instanceâthen the presence in the ashes of at least two individuals will have been demonstrated.â He paused and added gravely, âI think, Sloan, even a jury would agree with thatâif youâre going in for juries, that is.â
âIâm sure they would, Doctor,â responded Sloan with matching solemnity, although you never knew with juries. âActually, in this caseâââ
âStands to reason,â contributed Detective Constable Crosby. âDoesnât it?â
âYes, indeed,â said the pathologist hastily. âThe same applies if they weigh more thanâsayânine hundred grammes. Of course, the archaeologists can also deduce a good deal from what was buried with the body.â
âSo, I hope,â said Sloan piously, âcan detectives.â
âAnd grave goods,â continued Dr. Dabbe, âoften make it possible to distinguish between the centuries.â
âI think you might say,â murmured Sloan, âthat, in a manner of speaking, it is the grave goods which are our problem.â
The pathologist leaned forward. âTell me, Sloan, do they need to know if it was the noblest Roman of them all, then?â
âNot exactly, Doctor.â
Dr. Dabbe cocked his head alertly. âSay on, Inspector. This sounds interesting.â
âWe were hoping,â said Sloan, âthat something more thanâerâjust the fact of cremation might perhaps be determinable.â
âTeeth can tell you a lot,â offered Dabbe, âif youâre lucky.â
âItâs not the teeth weâre interested in,â said Sloan. âAt least, I donât think so.â
âThe provenance can be helpful,â said Dr. Dabbe briskly. âArchaeology and forensic medicine have a lot in common, you know.â
Sloan cleared his throat. âNot in this case, Doctor. At least, I donât think so.â
âThe urn and strata can often yield valuable information, too.â
âThey arenât really relevantâââ
âAnd,â said the doctor, warming to his theme, âyou can sometimes calculate the length of time that they have been buried byâââ
âThese havenât been buried, Doctor,â said Sloan gently.
âYet,â added Detective Constable Crosby, who had had the full history of the ashes explained to him in the car on the way from the Police Station to Mrs. Ottershawâs house at Mellamby.
The pathologist began to look very attentive. âSo, Sloan, if I were to tell you that sometimes the charcoal fragments can be a source of radio-carbon dating, you wouldnât be too excited?â
âNo, Doctor.â
âBut if I were to tell you that there were some poisons, especially the heavy metalsâthallium, for instanceâwhich did survive the cremation process, you would be interested?â
âVery.â
âIntriguing.â
âYes, Doctor.â Detective Inspector Sloan launched into an explanation of the metal pellet found in the ashes that the crematorium had handed to Tod Morton, and which the young undertaker had accidentally spilt.
âItâs not made of the alloy Vitallium, then,â said the doctor. âThe orthopods use that a lot but itâs non-magnetic.â
âNo, not
