Dead Lions is the second novel in the Slough House series by British author, Mick Herron. Slough House is where the spook screw-ups from MI5 who, for some reason or other, can’t be sacked, are sent. There they are set such tedious, mind-numbing tasks it’s hoped they will be fed-up enough to quit. Slough House doesn’t have a big staff, currently just seven under the control of Jackson Lamb. They had a bit of unexpected action a few months ago, so there are empty desks and a few new faces.

Ordinarily, there are no ops from Slough House: the Slow Horses can’t be trusted with anything that matters. But the recent death, on a bus, of Cold War spy, Dickie Bow has Jackson Lamb looking closer, and soon his smartest young spy, River Cartwright is in place in a sleepy Cotswolds village trying to track down a Russian agent. Meanwhile, two of Lamb’s slow horses are seconded by River’s nemesis at Regent’s Park, James (Spider) Webb, for “babysitting” duty in Russian oil talks. Is there a connection?

Once again, Herron gives the reader a fast-paced spy novel of a very different sort. The premise is original, and the execution is inspired. The characters are all credibly flawed, their dialogue is full of dry wit, and there is plenty of humour, most of it very black and very British, with an abundance of laugh out loud moments. There are twists and red herrings and the reader will find it hard not to cheer these misfits on as they do their best. Readers will be pleased to learn there are two and a half further volumes of this series for their entertainment and enjoyment. Another brilliant read!
