      By the time Amaia parked in the square next to the Lamia fountain, the drizzle had turned to a downpour. She pulled up the hood of her coat and hurried through the arch into Calle Pedro Axular, following the sound of raised voices. The anguish and urgency of those missed calls was reflected in Inspector Iriarte’s face as he struggled to contain a group of people intent upon approaching the patrol car. In the rear passenger seat, a weary-looking individual was sitting with his head propped against the rain-beaded window. Two uniformed officers were unsuccessfully attempting to cordon off the area surrounding a rucksack, which lay on the ground in the middle of a puddle. Amaia took out her phone and called for back-up as she hurried over to assist them. Just then, two more patrol cars advanced across the Giltxaurdi Bridge, distracting the angry mob, whose shouts were momentarily drowned out by the wailing sirens.

      Iriarte was soaked to the bone, and as he spoke to Amaia, he kept wiping his brow to stop the water going in his eyes. Deputy Inspector Etxaide appeared out of nowhere with a large umbrella, which he handed to them, then went to help the other officers pacify the crowd.

      ‘Well, Inspector?’

      ‘The suspect in the car is Valentín Esparza. His four-month-old daughter died last night while sleeping over at her maternal grandmother’s house. The doctor registered the cause as Sudden Infant Death Syndrome. So far, a tragedy. Except that yesterday, the grandmother, Inés Ballarena, paid a visit to the police station. Apparently, the baby was staying the night with her for the first time because it was the parents’ wedding anniversary, and they were going out to dinner. She was looking forward to it, and had even prepared a room for her. She fed the baby and put her down for the night, then fell asleep in front of the television in the sitting room next door, although she swears the baby monitor was on. She was woken by a noise, and went to look in on the baby – who from the doorway appeared sound asleep. Then she heard the crunch of tyres on gravel outside. She looked through the window in time to see a large, grey car driving away. Although she didn’t see the number plate, she assumed it was her son-in-law, as he has one just like it,’ said Iriarte, with a shrug. ‘She claims she checked the time and it was just gone two in the morning. She thought the couple must have driven by on their way home to see if any lights were on. This didn’t strike her as odd because they live nearby. She thought no more about it, and went back to sleep on the sofa. When she woke up, she was surprised not to hear the baby crying to be fed, so she went into the bedroom where she found the child dead. She was upset, she blamed herself, but when the doctor gave the estimated time of death as between two and three in the morning, she remembered waking up and seeing the car in the driveway. She now believes she was woken by an earlier noise inside the house. When Inés asked her daughter about this, she told her they had arrived home at around one thirty; she doesn’t drink usually, so a glass of wine and a liqueur after the meal had knocked her out. However, when Inés questioned the son-in-law, he became agitated, refused to answer, flew into a rage. He told her it was probably a couple of lovebirds looking for a secluded spot; it wouldn’t have been the first time. But then Inés remembered something else: she keeps her two dogs outside and they bark like crazy whenever a stranger comes near the house, but they didn’t make a sound last night.’

      ‘What did you do next?’ asked Amaia.

      Whether it was because they were intimidated by the police presence or simply wanted to get out of the rain, the crowd had retreated to the covered entrance of the funeral parlour. A woman at the centre of the huddle was embracing another, who was screaming and sobbing hysterically. It was impossible to make out what she was saying.

      ‘The woman screaming is the mother, the one with her arms around her is the little girl’s grandmother,’ Iriarte explained, following Amaia’s gaze. ‘Anyway, as I was saying, the grandmother was in a terrible state. She couldn’t stop crying while she was telling me her story. To begin with, I thought she was probably just trying to find an explanation for something that was difficult to accept. This was the first time they let her babysit, her first grandchild, she was distraught …’

      ‘But?’

      ‘But, even so, I called the paediatrician. He was adamant: Sudden Infant Death Syndrome. The baby was premature, her lungs weren’t properly formed, and she’d spent half of her short life in the hospital. Although they’d discharged her, this past week the mother had brought her to the surgery with a cold – only a sniffle, but in a premature, underweight baby, the doctor had no doubt about the cause of death. An hour ago, Inés turned up at the station again, insisting the girl had a mark on her forehead – round, like a button – which wasn’t there earlier. She said that when she pointed it out to her son-in-law, he snapped at her and insisted they close the coffin. So I decided to take a look for myself. As we entered the funeral parlour, we bumped into the father, Valentín Esparza, on his way out. He was carrying that rucksack’ – Iriarte pointed to the wet bundle sitting in a puddle – ‘and something about the way he was holding it struck me as odd. Not that I carry a rucksack myself, but it didn’t seem right.’ He clasped his hands to his chest to imitate the posture. ‘The minute he saw me, he turned pale and started to run. I caught up with him next to his car, and that was when he started to yell, telling us to leave him alone, saying he had to finish this.’

      ‘To take his own life?’

      ‘That’s what I thought. It occurred to me he might have a weapon in there …’

      Iriarte crouched down beside the rucksack, giving up the shelter of the umbrella, which he placed on the ground as a screen. He opened the flap, pulling the toggle to loosen the drawstring. The little girl’s dark, wispy hair revealed the soft spot on her head; her skin had that tell-tale pallor, although her mouth, slightly open, retained a hint of colour, giving a false impression of life, which held them transfixed until Dr San Martín leaned in, breaking the spell.

      While the pathologist removed the sterile wrapping from a swab, Iriarte gave him a summary of what he had told Amaia. Then San Martín crouched next to the child’s body and gently used the swab to remove the make-up that had been hastily applied to the bridge of the baby’s nose.

      ‘She’s so tiny.’ The sorrow in the usually imperturbable pathologist’s voice made Iriarte and Amaia look at him in surprise. Conscious of their eyes on him, he immediately busied himself examining the mark on the child’s skin. ‘An extremely crude attempt to cover up a pressure mark. It probably occurred at the precise moment when she stopped breathing, and is only visible to the naked eye now that lividity has set in. Give me a hand, will you?’ he said.

      ‘What are you going to do?’

      ‘I have to see all of her,’ he replied, with an impatient gesture.

      ‘Not here, please,’ said Iriarte. He indicated the crowd outside the funeral parlour. ‘You see those people? They’re the baby’s relatives, including her mother and grandmother. We’ve had enough difficulty controlling them as it is. If they see her dead body lying on the ground, they’ll go crazy.’

      ‘Inspector Iriarte is right,’ said Amaia, glancing towards the crowd then looking back at San Martín.

      ‘Very well, but until I have her on my slab I can’t tell you if there are any other signs of violence. Make sure you are thorough when you process the crime scene; I remember working on a similar case, where a mark on a baby’s cheek turned out to be made by a button on a pillowcase. Although I can give you one piece of information that might help.’ San Martín produced a small digital device from his Gladstone bag, holding it up proudly. ‘A digital calliper,’ he explained, pulling apart the two metal prongs, and adjusting them to measure the diameter
