I began going through journals； tearing out articles that needed to be filed。 I began working on an article I was due to write。 But I was not in the mood for any of it； and decided to check my e…mail to see if Lucy had left word about when she might make it to Richmond。 AOL announced I had mail waiting； and when I checked my box I felt as if someone had struck me。 The address deadoc awaited me like an evil stranger。
His message was in lowercase； with no punctuation except spaces。 It said； you think you re so smart。 I opened the attached file and once again watched color images paint down my screen； severed feet and hands lined up on a table covered with what appeared to be the same bluish cloth。 For a while I stared； wondering why this person was doing this to me。 I hoped he had just made a very big mistake as I grabbed the phone。
'Marino！' I exclaimed when I got him on the line。
'Huh？ What happened？' he blurted as he came to。
I told him。
'Shit。 It's three friggin' o'clock in the morning。 Don't you ever sleep？'
He seemed pleased； and I suspected he figured I wouldn't have called him if Wesley had still been here。
'Are you okay？' he then asked。
'Listen。 The hands are palm up；' I said。 'The photograph was taken at close range。 I can see a lot of detail。'
'Like what kind of detail？ Is there a tattoo or something？'
' Ridge detail；' I said。
Neils Vander was the section chief of fingerprint examination； an older man with wispy hair and voluminous lab coats perpetually stained purple and black with ninhydrin and dusting powder。 Forever in a hurry and prepossessed； he was from genteel Virginia stock。 Vander had never called me by my first name or referred to anything personal about me in all the years I had known him。 But he had his way of showing he cared。 Sometimes it was a doughnut on my desk in the morning or； in the summer； Hanover tomatoes from his garden。
Known for an eagle eye that could match loops and whorls at a glance； he was also the resident expert in image enhancement and； in fact； had been trained by NASA。 Over the years； he and I had materialized a multitude of faces from photographic blurs。 We had conjured up writing that wasn't there； read impressions and restored eradications； the concept really very simple even if the execution of it was not。
A high…resolution image processing system could see two hundred and fifty…six shades of gray； while the human eye could differentiate； at the most； thirty…two。 Therefore； it was possible to scan something into the puter and let it see what we could not。 Deadoc may have sent me more than he bargained for。 The first task this morning was to pare a morgue photograph of the torso with the one sent to me through AOL。
'Let me get a little more gray over here。' Vander said as he worked puter keys。 'And I'm going to tilt this some。'
'That's better；' I agreed。
We were sitting side by side； both of us leaning into the nineteen…inch monitor。 Nearby； both photographs were on the scanner； a video camera feeding their images to us live。
'A little more of that。' Another shade of gray washed over the screen。 'Let me bump this a tad more。'
He reached over to the scanner and repositioned one of the photographs。 He put another filter over the camera lens。
'I don't know；' I said as I stared。 'I think it was easier to see before。 Maybe you need to move it a little more to the right；' I added； as if we were hanging pictures。
'Better。 But there's still a lot of background interference I' d like to get rid of。'
'I wish we had the original。 What's the radiometric resolution of this thing？' I asked； referring to the system's capability of differentiating shades of gray。
'A whole lot better than it used to be。 Since the early days； I guess we've doubled the number of pixels that can be digitalized。'
Pixels； like the dots in dot matrix； were the smallest elements of an image being viewed； the molecules； the impressionistic points of color forming a painting。
'We got some grants； you know。 One of these days； I want to move us into ultraviolet imaging。 I can't even tell you what I could do with cyanoacrylate；' he went on about Super Glue； which reacted to ponents in human perspiration and was excellent for developing fingerprints difficult to see with the unaided eye。
'Well； good luck；' I said； because money was always tight no matter who was in office。
Repositioning the photograph again； he placed a blue filter over the camera lens； and dilated the lighter pixel elements； brightening the image。 He enhanced horizontal details； removing vertical ones。 Two torsos were now side by side。 Shadows appeared； gruesome details sharper and in contrast。
'You can see the bony ends。' I pointed。 'Left leg severed just proximal to the lesser trochanter。 Right leg' I moved my finger on the screen 'about an inch lower； right through the shaft。'
'I wish I could correct the camera angle； the perspective distortion；' he muttered； talking to himself； which he often did。 'But I don't know the measurements of anything。 Too bad whoever took this didn't include a nice little ruler as a scale。'
'Then I would really worry about who we were dealing with；' I mented。
'That's all we need。 A killer who's like us。' He defined the edges； and readjusted the positions of the photographs one more time。 'Let's see what happens if I superimpose them。'
He did； and the overlay was amazing； bone ends and even the ragged flesh around the severed neck； identical。
'That does it for me；' I announced。
'No question about it in my mind；' he agreed。 'Let's print this out。'
He clicked the mouse and the laser printer hummed on。 Removing the photographs from the scanner； he replaced them with the one of the feet and hands； moving it around until it was perfectly centered。 As he began to enlarge images； the sight became even more grotesque； blood staining the sheet bright red； as if it had just been spilled。 The killer had neatly lined up feet like a pair of shoes； hands side by side like gloves。
'He should have turned them palm down；' Vander said。 'I wonder why he didn't？'
Using spatial filtering to retain important details； he began eliminating interference； such as the blood and the texture of the blue table cover。
'Can you get any ridge detail？' I asked leaning so close； I could smell his spicy aftershave。
'I think I can；' he said。
His voice was suddenly cheerful； for there was nothing he liked better than reading the hieroglyphics of fingers and feet。 Beneath his gentle； distracted demeanor was a man who had sent thousands of people to the penitentiary； and dozens to the electric chair。 He enlarged the photograph and assigned arbitrary colors to various intensities of gray； so we could see them better。 Thumbs were small and pale like old parchment。 There were ridges。
'The other fingers aren't going to work；' he said； staring； as if in a trance。 'They're too curled for me to see。 But thumbs look pretty darn good。 Let's capture this。' Clicking into a menu； he saved the image on the puter's hard disk。 'I'm going to want to work on this for a while。'
That was his cue for me to leave； and I pushed back my chair。
'If I get something； I'll run it through AFIS right away；' he said of the Automated Fingerprint Identification System； capable of paring unknown latent prints against a databank of millions。
'That would be great；' I said。 'And I'll start with HALT。'
He gave me a curious look； because the Homicide Assessment and Lead Tracking System was a Virginia database maintained by the state police in conjunction with the FBI。 It was the place to start if we suspected the case was local。
'Even though we have reason to suspect the other cases are not from here；' I explained to him； 'I think we should search everything we can。 Including Virginia databases。'
Vander was still making adjustments； staring at the screen。
'As long as I don't have to fill out the forms；' he replied。
In the hallway were more boxes and white cartons marked EVIDENCE lining either side and stacked to the ceiling。 Scientists walked past； preoccupied and in a hurry； paperwork and samples in hand that might send someone to court for murder。 We greeted ea
