There are three threads going on in this story that switch back and forth between Britain and Canada. Each story puts characters' lives in jeopardy. Dominic and his brother Damien nearly die on a hummock of reeds in the middle of a lake of rising water, enduring bitter cold, after an accident with their canoe. Lindy and Danny Maik nearly die at the hands of Peter Mahler, a man who is intent on framing Ray Hayes for Lindy's murder, thus getting revenge. Having spent time together in prison, tormenting each other, both now out, Peter's revenge would be to put Ray, who suffers from carcerophobia, back in prison for life. Danny sets out to find the missing Lindy, thereby leading Mahler to the cottage where Ray is holding them.
Newly promoted Lauren Salter is out to solve her first case, the murder of Wattis Wright, who had supposedly just finished selling the rights to the dance moves for the Shammalars, which he had not developed of his own, but with Jennie Wynn. She uses all the moves Dominic and Danny have shown her to deftly figure out and land the killer. (Hallelujah...Danny and Lauren seem to come together in the resolution of this one.)
And Traz Perez and his new lady love come to the rescue of the stranded brothers, after taking part in a chase of the exalted whooping cranes who travel from Aransas, Texas Wildlife Refuge to Wood Buffalo National Park in the Northwest Territories of Canada for nesting. Damien had joined the project with Annie Prior, who then drowns in the Class Six rapids of the Little Buffalo River. Being pursued by unknown men, Damien disables their inReach devices and goes silent. Dominic goes in to find him, when the RCMP and Park Service will not start a search. In stead of the publicized project however, Annie had made a trade with Gaetan Robideau, a Dene, to give up picture taken from cameras attached to the migrating cranes for the location of sites of generations of Dene feasting, an anthropological unknown to date. The pictures would reveal the issues with water in the Territories, being destroyed by human activities and global warming, which Robideau needs to use in his campaign to save the land.
An excellent story, once again, in this fascinating series, also about some lovely birds, and the environmental issues surrounding us. Hopefully there will be another installment in the near future.
